lbase64: compile with -fPIC

Some architectures (e.g. x86_64, MIPS, microblaze, or1k) require to
build with -fPIC to build a shared library, but the lbase64 build
system doesn't add it. Therefore, we add it in CFLAGS.

libressl: fix musl build with older kernel headers

musl provides its own SYS_getrandom definition, but not GRND_NONBLOCK.
This breaks the build with kernel headers older than v3.17. Add a patch
adding a local definition of GRND_NONBLOCK to fix the build.

The following defconfig reproduces the build failure:

BR2_x86_pentium_mmx=y
BR2_TOOLCHAIN_BUILDROOT_MUSL=y
BR2_KERNEL_HEADERS_3_12=y
BR2_PACKAGE_LIBRESSL=y

The getentropy_linux.c file is in upstream tarball, but not in its git
repository. It originates from OpenBSD. For this reason the patch is

overrides the setUp method.

qt: Allow enabling of QtWebKit with GCC 6+

package/bridge-utils: fix headers path

Currently, bridge-utils wants to grap the headers from the linux-headers
package, so we point it directly there, as has been the case since we
first added bridge-utils in 2003 (c8eea31d3f), and then further refined
in 2005 (178a317d26) which is the first moment we pointed to the linux-
headers directory.

However, ther are two things wrong with that.

First, the headers are not directly in $(LINUX_HEADERS_DIR). Instead,
they are in a sub-directory thereof. So, we could not have found them
the way we are doing now.

Second, this definitely does not work when using an external toolchain,
because there is not linux-headers package enabled then.

Yet, against all odds, bridge-utils has valiantly deflected all rocks
thrown its way, day-in day-out building without any issue in every
autobuilders it's been confronted with. Good boy, good boy. :-)

And indeed, it turns out that the required headers are easily found from
within the sysroot of the toolchain. Wonders! :-)

But there's still a gotcha: the default search path is still a hard
coded path pointing to the installed kernel source tree on the host.

So, we still have to pass this option, but we can simply point to the
sysroot.

arc/bfin: remove 60x cores

Those cores are not supported in upstream gcc, not even in master.

The only toolchain that supported those core was the 2014R1 ADI
rebuilt toolchain, but we removed it in 311bc13 (toolchain: kill
ADI Blackfin toolchain) because there was too many issues with it.
ADI has not released any newer toolchain since then.

There is little hope for those cores now, so remove them.

Support for those cores has been useless and unusable for a while
without nobody noticing, therefore we intentionally skip adding
Config.in.legacy. This would require keeping code in
arch/Config.in.bfin since the options being removed are inside a
choice...endchoice block.

arch: add option to disable internal toolchain backend

Some architectures or specific cores do not have support in upstream
gcc. Currently, they are individually listed as exclusions in the
toolchain choice.

This poses a maintainance burden, as the knowledge about what gcc
version supports what architecture is split across many places: the
toolchain choice, the gcc version choice, the external toolchains.

As a first step, add a blind option that architectures or individual
cores may select to indicate they lack support in our internal backend.

Actual use of the option will come in followup patches.

flex: Fix segfault of stage1flex when host has glibc 2.26 or newer

When the host uses glibc 2.26 or newer, Flex will try to use the
newly-introduced reallocarray() function, but as it would not define
_GNU_SOURCE a segmentation fault would occur later on due to the
compiler assumming that the function is implicitly defined.

This issue manifests itself due to a crash of "stage1flex" during the
Flex bootstrap:

  ./stage1flex   -o stage1scan.c ./scan.l
  make[2]: *** [Makefile:1725: stage1scan.c] Segmentation fault (core dumped)

This imports the patch from the upstream Git repository, and adds flags
in the .mk file to rebuild the Autotools scripts and support files. Due
to the latter, the patch to disable the documentation is changed so it
modifies the .am file instead.

package/flex: disable reallocarray

This doesn't compile with glibc 2.26 where reallocarray() as been introduced.

It's a nasty issue, when reallocarray() is available for the target, flex will
build a small tool called stage1flex for the host (using _FOR_BUILD) but with
the config.h generated for the target.

When the host doesn't have a glibc >= 2.26, reallocarray() is never defined
while building stage1flex:

misc.c:147:8: warning : implicit declaration of function « reallocarray »
[-Wimplicit-function-declaration]
  mem = reallocarray(NULL, (size_t) size, element_size);
        ^~~~~~~~~~~~
misc.c:147:6: warning : assignment makes pointer from integer without a cast
[-Wint-conversion]
  mem = reallocarray(NULL, (size_t) size, element_size);
      ^

Disable reallocarray for now, reallocarray() support may be
enabled in a followup patch.

Fixes:
stage1flex-misc.o: In function `allocate_array':
misc.c:(.text+0x38f): undefined reference to `reallocarray'
stage1flex-misc.o: In function `reallocate_array':
misc.c:(.text+0xc8a): undefined reference to `reallocarray'

package/diffutils: disable getopt_long replacement with glibc

Since glibc >= 2.26, don't try to use getopt_long replacement bundled
with diffutils. It will conflict with the one from glibc.
The getopt copy bundled in glibc has been updated with the one from gnulib.

After a lot of warnings...
Fixes:
xstrtol-error.c: In function 'xstrtol_error':
xstrtol-error.c:84:26: error: invalid use of undefined type 'struct rpl_option'

package/gcc: enable float128 on powerpc64le with glibc >= 2.26 toolchains

float128 is now required on powerpc64le with glibc >= 2.26 toolchains.

Fixes:
running configure fragment for sysdeps/gnu
running configure fragment for sysdeps/powerpc/powerpc64le
checking if [...]powerpc64le-buildroot-linux-gnu-gcc supports binary128 floating point type... no
checking if the target machine is at least POWER8... yes
configure: error: ***  binary128 floating point type (GCC >= 6.2) is required on powerpc64le.

In order to prepare the glibc bump to this version, we enable
binary128 floating point in gcc. This require at least gcc >= 6.2.

Disable gcc 4.x and 5.x for internal toolchain.

package/glibc: needs kernel headers >= 3.10 on powerpc64le

Since glibc 2.26, kernel headers >= 3.10 are needed on powerpc64le [1].
In order to prepare the glibc bump to this version, we don't allow to
build a Buildroot toolchain with kernel headers older than 3.10.

utils/config: new script to manipulate .config files on the command line

Default prefix is set to `BR2_` but may be overidden by setting
BR2_PREFIX.

Example usage:

Enable `BR2_PACKAGE_GNUPG`:
./utils/config --package --enable GNUPG

Check state of config option `BR2_PACKAGE_GNUPG`:
./utils/config --package --state GNUPG
y

Enable `BR2_PACKAGE_GNUPG`:
./utils/config --package --disable GNUPG

Set `BR2_TARGET_GENERIC_ISSUE` to "Welcome":
./utils/config --set-str  TARGET_GENERIC_ISSUE "Welcome"

Copied from the Linux kernel (4.13-rc6) source code and adapted to
Buildroot.
