webkitgtk24: use the correct Config.in option for NEON

In order to enable JIT support on ARM, webkitgtk24 currently looks at
BR2_ARM_ENABLE_NEON, which is not correct: BR2_ARM_CPU_HAS_NEON should
be used instead.

The BR2_ARM_ENABLE_NEON is only visible for cores that select
BR2_ARM_CPU_MAYBE_HAS_NEON, in order to allow to specify if his
particular SoC has chosen to integrate NEON or not. And if so,
BR2_ARM_CPU_HAS_NEON gets selected.

BR2_ARM_CPU_HAS_NEON is in fact selected in two different ways:

 - Either directly by the CPU core selection, if NEON is mandatory in
   this CPU core.

 - Or by BR2_ARM_ENABLE_NEON, for CPU cores where NEON support is
   optional.

So really, BR2_ARM_CPU_HAS_NEON is what should be used by packages.

glib-networking: specify GIO_MODULE_DIR for target

Since the upgrade to pkgconf 0.9.12 all directories and variables with

libglib2 uses a giomoduledir=${libdir}/gio/modules variable in
gio-2.0.pc, which when expanded via sysroot by pkgconf at configure time
points to the staging directory (via libdir expansion).

python-numpy: uClibc patch to avoid ldexpl and frexpl

It turns out that uClibc only enables the long double math functions
for some architectures (god know why, so what if long double is the
same as double, these functions should still be defined). Since
python-numpy links with those functions, the module will fail to load
on ARM, MIPS and SH.

However, python-numpy actually checks for each function if it is really
available. Only, it overrides that check for ldexpl and frexpl when
long double is the same as double (i.e. in exactly the case the uClibc
doesn't have these functions).

So add another exception for this.

option is enabled.

dtc: add host build

Having a host variant of dtc is needed for example for U-Boot, which
uses the Device Tree for a number of platforms.

In addition, now that we have a proper host-dtc package, it is no
longer needed for the linux package to install the host dtc compiler:
users interested in having the host dtc compiler can simply enable
this package.

A Config.in.host option is added to build host-dtc, because the
initial reason why the host DTC built by the kernel was installed in
$(HOST_DIR)/usr/bin (commit 707d44d0a28906ebda49584dd5f55985406f0bde

configs: fix build of calao_qil_a9260_defconfig

The Barebox, AT91Bootstrap and Linux patches for the Calao QIL A9260
board are all located in the same directory, board/calao/qil-a9260/,
with only a prefix to indicate to which component they apply.

Unfortunately, since commit 0eba4759fab9d093afacac77a0ac31f1f0b3cceb
("packages: apply custom patches using *.patch instead of
<pkg>-*.patch"), the logic to apply custom patches in Barebox and
AT91Bootstrap has been changed from applying <package>-*.patch to
applying *.patch (in order to be consistent with what we do for all
packages in Buildroot).

However, this had the effect of trying to apply both the AT91Bootstrap
and Barebox patches on both packages, which obviously cannot work.

This commit fixes that by moving patches around, and switching to use
BR2_GLOBAL_PATCH_DIR for all of Barebox, AT91Bootstrap and Linux
patches.

In addition, the defconfig was not specifying explicitly which Barebox
version to use, so right now it's trying to use Barebox 2015.09, on
which the board-specific patch does not apply. So we've forced to use
Barebox 2012.08, which was the lastest release available at the time
the defconfig was initially contributed.

("packages: apply custom patches using *.patch instead of
<pkg>-*.patch"), the logic to apply custom patches in Barebox and
AT91Bootstrap has been changed from applying <package>-*.patch to
applying *.patch (in order to be consistent with what we do for all
packages in Buildroot).

However, this had the effect of trying to apply both the AT91Bootstrap
and Barebox patches on both packages, which obviously cannot work.

This commit fixes that by moving patches around, and switching to use
BR2_GLOBAL_PATCH_DIR.

python-numpy: re-enable for uClibc

In commit b0f025386f6861fdc21e38e3a33b65669276f2c2 a patch was added
to make sure that python-numpy does work in uClibc. This patch was
needed for the x86 architecture, because uClibc in fact does support
fenv for x86. However, we don't turn on this support in our uClibc
config. Because the Config.in depends still allowed uClibc for x86,
this lead to a built failure, which lead to the fix in commit b0f02538.
But since this fix also fixes it for all other (supported)
architectures, we can just remove the !uClibc dependency completely.

This is also propagated to the reverse dependency in opencv3.

ccache: support changing the output directory

When building in a different output directory than the original build,
there will currently be a lot of ccache misses because in many cases
there is some -I/... absolute path in the compilation. Ccache has an
option CCACHE_BASEDIR to substitute absolute paths with relative paths,
so they wil be the same in the hash (and in the output).

Since there are some disadvantages to this path rewriting, it is made
optional as BR2_CCACHE_USE_BASEDIR. It defaults to y because the
usefulness of ccache is severely reduced without this option.

In addition to CCACHE_BASEDIR, we also substitute away the occurences
of $(HOST_DIR) in the calculation of the compiler hash. This is done
regardless of the setting of BR2_CCACHE_USE_BASEDIR because it's
quite harmless.

ccache: use mtime for external toolchain, CONF_OPTS for internal toolchain

Our current ccache disables hashing of the compiler executable itself,
because using the default 'mtime' doesn't work in buildroot: we always
rebuild the compiler, so the mtime is always different, so the cache
always misses.

However, in the current situation, if a user changes the compiler
configuration (which would result in the compiler generating different
object files than before) and does 'make clean all', ccache may in fact
reuse object files from the previous run. This rarely gives problems,
because
(1) the cache expires quite quickly (it's only 1GB by default),
(2) radically changing compiler options will cause cache misses because
    different header files are used,
(3) many compiler changes (e.g. changing -mtune) have little practical
    effect because the resulting code is usually still compatible,
(4) we currently don't use CCACHE_BASEDIR, and almost all object files
    will contain an absolute path (e.g. in debug info), so when
    building in a different directory, most of it will miss,
(5) we do mostly build test, and many of the potential problems only
    appear at runtime.
Still, when ccache _does_ use the wrong cached object files, the
effects are really weird and hard to debug. Also, we want reproducible
builds and obviously the above makes builds non-reproducible. So we
have a FAQ entry that warns against using ccache and tells the user to
clear the cache in case of problems.

Now that ccache is called from the toolchain wrapper, it is in fact
possible to at least use the 'mtime' compiler hash for the external
toolchain and for the host-gcc. Indeed, in this case, the compiler
executable comes from a tarball so the mtime will be a good reference
for its state. Therefore, the patch (sed script) that changes the
default from 'mtime' to 'none' is removed.

For the internal toolchain, we can do better by providing a hash of
the relevant toolchain options. We are only interested in things that
affect the compiler itself, because ccache also processes the header
files and it doesn't look at libraries because it doesn't cache the
link step, just compilation. Everything that affects the compiler
itself can nicely be summarised in $(HOST_GCC_FINAL_CONF_OPTS). Of
course, also the compiler source itself is relevant, so the source
tarball and all the patches are included in the hash. For this purpose,
a new HOST_GCC_XTENSA_OVERLAY_TAR is introduced.

The following procedure tests the ccache behaviour:

 Use this defconfig:
BR2_arm=y
BR2_CCACHE=y

 make
 readelf -A output/build/uclibc-1.0.6/libc/signal/signal.os
-> Tag_CPU_name: "ARM926EJ-S"

 Now make menuconfig, change variant into BR2_cortex_a9

 make clean; make
 readelf -A output/build/uclibc-1.0.6/libc/signal/signal.os
-> Tag_CPU_name: "ARM926EJ-S"
 should be "Cortex-A9"

After this commit, it is "Cortex-A9".

gcc: use toolchain wrapper

We have a toolchain wrapper for external toolchain, but it is also
beneficial for internal toolchains, for the following reasons:

1. It can make sure that BR2_TARGET_OPTIMIZATION is passed to the
   compiler even if a package's build system doesn't honor CFLAGS.
2. It allows us to do the unsafe path check (i.e. -I/usr/include)
   without patching gcc.
3. It makes it simpler to implement building each package with a
   separate staging directory (per-package staging).
4. It makes it simpler to implement a compiler hash check for ccache.

The wrapper is reused from the external toolchain. A third CROSS_PATH_
option is added to the wrapper: in this case, the real executable is in
the same directory, with the extension .real.

The creation of the simple symlinks is merged with the creation of the
wrapper symlinks, otherwise part of the -gcc-ar handling logic would
have to be repeated.

The complex case-condition could be refactored with the one for the
external toolchain, but then it becomes even more complex because
they each have special corner cases. For example, the internal
toolchain has to handle *.real to avoid creating an extra indirection
after host-gcc-{final,initial}-rebuild.

Instead of creating the .real files, it would also have been possible
to install the internal toolchain in $(HOST_DIR)/opt, similar to what
we do for the external toolchain. However, then we would also have to
copy things to the sysroot and do more of the magic that the external
toolchain is doing. So keeping it in $(HOST_DIR)/usr/bin is much
simpler.

Note that gcc-initial has to be wrapped as well, because it is used for
building libc and we want to apply the same magic when building libc.

legal-info: allow to declare the actual sources for binary packages

The FOO_SITE/FOO_SOURCE variables usually point to a tarball containing
source code.

For the downloaded external toolchains this is not true, the "source"
tarball actually contains binaries. This is fine for making Buildroot
work, but for legal-info we really want to ship real source code, not
binaries.

Luckily, some (hopefully all) toolchain vendors publish a downloadable
tarball containing the source code counterpart for their binary
packages.

Here we allow the user to declare the URL of this other tarball in the
pair of variables FOO_ACTUAL_SOURCE_TARBALL (by default equal to
FOO_SOURCE) and FOO_ACTUAL_SOURCE_SITE (by default equal to FOO_SITE).
If the "actual source" package can be downloaded from the same
directory as the binary package, then only FOO_ACTUAL_SOURCE_TARBALL
needs to be set.

Note this change is not strictly toolchain-specific: it might be useful
for other packages that happen to ship binaries in the same way.

[Thomas:
  - remove "the source code has not been saved" warning that could
    never be triggered due to how the conditions were
    organized. Discussed with Luca live during the meeting.]

pkg-generic: prevent _SITE URLs with a trailing slash

A trailing slash in FOO_SITE is useless, since Buildroot automatically adds
a slash between FOO_SITE and the filename as appropriate.

Moreover it is potentially harmful, which led to introducing a workaround
to strip them:

    commit 1cbffbd015106ea90fe49e27433375769dc1035b
    Author: Shawn J. Goff <shawn7400@gmail.com>
    Date:   Fri Apr 12 09:40:30 2013 +0000

        eliminate double slashes caused by FOO_SITE ending in a slash

        When a FOO_SITE variable ends in a slash and gets joined with a
        FOO_SOURCE variable like $(FOO_SITE)/$(FOO_SOURCE), the resulting URI
        has a double slash. While double-slashes are fine in unix paths, they
        are reserved in URIs - the part following '//' must be an authority.

So let's ban trailing slashes entirely. They have all been removed in
a 7b0e757fb85fd, now add a check to error out loudly in case a new one
is added.

Example commands to test this check:

  $ make busybox-dirclean busybox-source
  rm -Rf /home/murray/devel/buildroot/output/build/busybox-1.23.2
  busybox-1.23.2.tar.bz2: OK (md5: 7925683d7dd105aabe9b6b618d48cc73)

  rm -Rf /home/murray/devel/buildroot/output/build/busybox-1.23.2
  BUSYBOX_SITE (http://www.busybox.net/downloads/) cannot have a trailing slash

toolchain-external: strip trailing slash from autogenerated FOO_SITE

Trailing slashes are going to be declared illegal from FOO_SITE
variables.

But Buildroot internally generates such a variable when using a custom
external toolchain (i.e. BR2_TOOLCHAIN_EXTERNAL_CUSTOM). This is
because TOOLCHAIN_EXTERNAL_SITE is set to
$(dir $(call qstrip,$(BR2_TOOLCHAIN_EXTERNAL_URL))), and $(dir)
leaves a trailing slash.

Fix it using patsubst, just like linux and the bootloaders do.

zxing-cpp: new package, replacing zxing

ZXing was hosted on Google Code, which is a closing. The current link
was already redirecting to the github repo.

But upstream is no longer supporting the cpp bindings, it's now a Java
library/application.

A fork has been created from the latest cpp source of the original
upstream. So this commit creates a new package, zxing-cpp, and adds
Config.in.legacy handling for the old zxing pakcage that is removed.

[Thomas:
  - add a patch that improves the CMakeLists.txt file to add
    installation rules. This allows to remove the manual installation
    logic from zxing-cpp.mk.
  - make libiconv a normal optional dependency. No need to involve
    BR2_ENABLE_LOCALE in the condition, since libiconv can only be
    enabled when !BR2_ENABLE_LOCALE.
  - bump to the latest upstream version.
  - add hash file.]
