dnsmasq: static linking with lua doesn't need -ldl

Fixes http://autobuild.buildroot.net/results/77e/77e4123a3ddc934efedf4b09adc2436421ee70b3/

liblua only uses libdl when dynamic linking is used, and certain toolchains
(E.G.  bfin) doesn't provide a libdl - So only link against it if it is
needed.

At the same time change it pass the library in LIBS instead of LDFLAGS so it
ends up at the end of the linker cmdline.

hdparm: prevent package makefile from stripping the hdparm binary

Packages shouldn't strip executables by themselves, so that Buildroot

build on Blackfin FLAT where stripping actually doesn't work because

gettext: optimize build time

This commit significantly reduces the build time of host-gettext and
gettext, by using the capacity of gettext to handle build things in a
certain subdirectory:

 - For the host variant of gettext, we only need the gettext-tools,
   available in the directory of the same name in the gettext sources.

 - For the target variant of gettext, we only need the gettext library
   libintl, available in the gettext-runtime directory in the gettext
   sources.

So by using appropriate values of GETTEXT_SUBDIR and
HOST_GETTEXT_SUBDIR, we only build what's necessary. Moreover, by
manually patching gettext-tools/Makefile.in and
gettext-runtime/Makefile.in, we make sure to not build and install
things like examples, documentation and so on.

In addition to this, these changes avoid the need to autoreconfigure
the gettext package, which was particularly long.

Thanks to these changes, the build time of gettext goes from 1 minutes
and 37 seconds to just 24 seconds, and the build of host-gettext goes
from 2 minutes and 18 seconds to 1 minute and 13 seconds.

toolchain-external: do not pass TOOLCHAIN_EXTERNAL_CFLAGS for kernel headers check

When getting the sysroot used for the kernel headers version check,
passing TOOLCHAIN_EXTERNAL_CFLAGS causes a problem when used with
multilib toolchains, where only the main sysroot has the header files,
and the other sysroots only have the libraries.

Since the kernel headers version used is normally the same for all
sysroots, this commit solves this problem by removing the
TOOLCHAIN_EXTERNAL_CFLAGS argument when calling
toolchain_find_sysroot, so that it returns the main sysroot, in which

external toolchains (i.e the built-in profiles, such as Linaro,
CodeSourcery and al.), making the assumption that the Buildroot
developers will do the right selection.

However, it is quite nice when bumping external toolchains to have

uclibc: add patches to fix MIPS __SIGRTMAX and SIG127

Add two uClibc 0.9.33.2 patches which fix issues relating to high signal
number handling on MIPS.

The first patch (0056) fixes _NSIG (and as a result __SIGRTMAX) to match
glibc. This fixes GDB on MIPS with uClibc, which cannot handle
__SIGRTMAX == 128 and emits the error:
GDB bug: target.c (gdb_signal_from_host): unrecognized real-time signal
This patch is from uClibc commit 2da958760f79 (MIPS: set _NSIG to
128, not 129. This matches glibc.) and applies without conflicts.

The second patch (0057) fixes the wait status macros to correctly
interpret status 0x007f on MIPS (other arches don't have signal 127).
This patch is from uClibc commit 4a96b9486871 (bits/waitstatus.h:
correctly interpret status 0x007f on MIPS) and applies without
conflicts.

package infra: remove duplicates in dependencies list

Currently, we just use what a package declares as its dependencies.

But some packages may declare the same depdency more than once. For
example, php has two options to add SQL support: 'mysql' or 'mysqli',
which are not exclusive. So, php.mk has mysql twice as a dependency.

Although that does not cause any grievance for make, we end up generating
dependency graphs where this duplicate dependency is visible.

Add an intermediary variable which contains the $(sort)-ed list of the
dependencies, thus eliminating any duplicates.

This has the side effect of also sorting the list, which is probably
good for reproducibility anyway.

Generate an asciidoc table that can be included in the manual, that
lists the existing virtual packages, the corresponding symbols, and

The core of this change is the addition of a new formatter for virtual

bunch of corner cases:
  - provider is not a package, but is sub-options of a package
  - such a sub-option may be itself 'select'-ed by one or more
    other sub-options
  - legacy packages should not be considered as a provider

Those cases are real:
  - sub-options of mesa3d provide EGL or GLES
  - selected sub-options of mesa3d provide GL
  - udev is a legacy package, but it provides udev

support/scripts: introduce a symbol formatter to generate package lists

Currently, we can generate two different tables of packages:
  - a single-column table with the symbols' prompts,
  - a two-column table with the symbols' prompts and locations in the
    menuconfig.

For virtual packages, this is not enough, since we will have to display
more columns, with different content:
  - the virtual package name (but such symbols do not have a prompt)
  - the symbol name
  - the providers for the virtual package

So, instead of having a single function that knows how to generate any
table, introduce a formatter function that is passed as argument to,
and called by format_asciidoc_table(). Such formatter functions are
responsible for providing:
  - the layout of the table (number of columns, column arrangement),
  - the formatted header line,
  - a formatted line for a symbol.

What the formatter should ouput depends on its arguments:
  - if none are passed, the layout is returned,
  - if the header label is passed, it returns the formatted header line,
  - otherwise, it returns the formatted line for a symbol.

Two formatter functions are introduced in this changeset, to replace the
current 'sub_menu' feature:

support/scripts: who's responsible to decide what is a package

When generating the package lists, the responsibility to decide what is
actually a package symbol is currently split between the _is_package(),
the get_symbol_subset() and the format_asciidoc_table() functions.

The two latter functions check that an item is really a symbol, and that
is has a prompt.

While this is currently correct for real packages, this will no longer
be the case when we also generate a list of virtual packages, since they
do not have a prompt.

Move the responsibility to verify that a symbol is indeed a package symbol
to _is_package(), so it's all in one place, and makes it easier to change
for virtual packages.

support/scripts: do not display virtual packages in generated lists

If a package has both a 'real' and a 'virtual' definition, consider it
is a virtual package and do not display it in the generated package list.

This is the case for jpeg and cryptodev, that are virtual packages, but
also real (but empty) packages used to provide a prompt to enable/disable
a choice to select an implementation. In this case, we do not want to
list the virtual packages, but only their implementations.

So, consider packages that are both real and virtual as virtual packages.

support/scripts: prepare handling virtual packages in generated lists

Prepare to tell apart real packages from virtual packages.

Currently, the code implicitly recognises only real packages, and
discards virtual packages, because of the heuristic used to recognise
whether a symbol is a package:

  - for real package:
    - symbols  : BR2_PACKAGE_FOO
    - .mk files: foo.mk
  - for virtual packages:
    - symbols  : BR2_PACKAGE_HAS_FOO
    - .mk files: foo.mk

The current heuristic is to check for each symbol if a corresponding .mk
file exists, by stripping 'BR2_PACKAGE_' from the beginning of the symbol,
converting the result to lowercase, and checking if a .mk file exists.

So, as a side effect, it completely misses the virtual packages [*], which
is pretty nice since we get a list with only real packages that the user
can indeed select and see in the menuconfig.

[*] Except for 'cryptodev' and 'jpeg' which are both virtual packages and
normal packages. Except they are not normal packages, they are used to
display a choice of the implementation to use. This case will be fixed in
follow-up patches.

Since we'll soon need to also output the table of virtual packages, we
need to teach the _is_package() function to recognise them as well.

This patch is the first step into that direction: it introduces a new
function _is_real_package() that is just a wrapper to _is_package(), which
gains a new parameter, being the type of packages to filter on.

No behavioural change is made in this patch, it is just a preparatory
patch.

package/mesa3d: rename the prompt

Rename the prompt for mesa3d so that it matches what we usually do
for prompts of packages: just name the package in lower case.

This will help generate nicer tables in the generated packages list,
both in existing tables, and in the upcoming table of virtual packages.

package/jpeg: make it behave more like other virtual packages

Currently, the virtual package jpeg is a special virtual package,
as it offers a choice for its implementation, rather than letting the
user enable them manually.

In so doing, it defines its _HAS option as a 'def_bool y' rather than
letting each implementation 'select' it.

Since we are going to generate a list of virtual packages and their
providers, this defeats the heuristic used to find providers.

Coming with an alternate heuristic that also matches the jpeg
package is quite complex, so better and easier to make it look more
like any other virtual package.
