3d997bf7bc gcc: switch to gcc 4.8.x as the default compiler version
gcc 4.7.x is going to be retired soon, and now that gcc 4.9.0 is out,
it's time for Buildroot to switch to gcc 4.8.x as the default gcc
compiler version.

See https://gcc.gnu.org/ml/gcc/2014-05/msg00324.html for details about
gcc 4.7.x life cycle.

a957e1b265 gcc: fix xtensa overlay application
gcc build scripts use wrong variable name to specify xtensa overlay
application command. As a result gcc is built with the default overlay,
which leads to obscure failures later in the build process.

xtensa toolchain needs an additional configuration for a specific core
variant we're building for. This configuration is called 'overlay' and
is an archive with files for binutils, gcc and gdb that replace
corresponding files in toolchain components.

dd1c4f65b1 gcc: xtensa: fix __builtin_frame_address use with shared libgcc
The xtensa port uses __xtensa_libgcc_window_spill in libgcc to implement
__builtin_frame_address. This symbol is local/hidden in libgcc. This is not a
problem when linking against static libgcc. But g++ defaults to
-shared-libgcc, thus breaking link against C++ shared libraries that are using
__builtin_frame_address as follows:

ld: test: hidden symbol `__xtensa_libgcc_window_spill' in .../libgcc.a(lib2funcs.o) is referenced by DSO

Add upstream patches that make libgcc_s.so a linker script that links in
unresolved symbols from the static libgcc, similar to the ARM and PowerPC
ports.

12d150727a Strip *.so* and not only executable files
Our current stripping strategy requires that shared libraries have the
executable permission. However, this is by far not something
recognized as a standard behavior: Debian/Ubuntu distributions for
example do not have executable permissions on their
libraries. Therefore, pushing to upstream packages fixes that add the
executable permissions is not easy.

As a result, this commit improves the stripping logic so that it not
only strips the files that are executable, but also the ones that
match '*.so*', which should match both the shared libraries and the
dlopen()'able plugins, as long as they have a .so extension.

Thanks to this addition, a number of manual "chmod +x" done by various
packages can be removed.

ba4ad9d27c deprecated handling: introduce BR2_DEPRECATED_SINCE_xxxx_xx
In order to keep better track of when a feature got deprecated, and hence
when it can be removed, a new set of symbols BR2_DEPRECATED_SINCE_xxxx_xx is
introduced. These symbols are automatically selected when BR2_DEPRECATED is
selected, and thus are transparent to the user.
A deprecated feature will no longer depend on BR2_DEPRECATED directly, but
rather on the appropriate BR2_DEPRECATED_SINCE_xxxx_xx. If that symbol does
not yet exist, it has to be created in Config.in.
When removing a deprecated feature, one should also check whether this was
the last feature using the BR2_DEPRECATED_SINCE_xxxx_xx symbol, in which
case the latter can be removed from Config.in.

A followup patch will make sure the overview is added to the list of
deprecated features in the manual, so that a buildroot core developer can
easily determine which features to remove in a given development cycle.

530777aaeb gcc: provide option to enable mudflap support
The mudflap library is only useful if one uses the -fmudflap gcc
option to do more checks on pointers/arrays. This commit adds an
option to enable/disable mudflap support at the gcc level. By default,
it is disabled, which saves a little bit of build time compared to the
default of gcc which consists in enabling mudflap support.

Since mudflap is now disabled by default, and ensured to never be enabled
on platforms where it is not available, some gcc.mk code that was used to
disable mudflap in problematic configurations can be removed.

Whether -fmudflap is used when building is left to the user.

094fd1d01d gcc: force symlink creation
The HOST_GCC_CONFIGURE_SYMLINK creates a symbolic link
$(@D)/build/configure -> $(@D)/configure for each build step of
gcc. However, it was only using 'ln -s' and not 'ln -sf', which was
causing problems when doing 'make host-gcc-final-reconfigure' for
example, because the configure commands (including this macro) are
being re-executed, but the symbolic link already exists.

Changing this symbolic link creation to 'ln -sf' fixes this problem.

df9bbb779f gcc/gcc-final: use the common HOST_GCC_CONFIGURE_SYMLINK macro
Each stage of the gcc build needs to make a small dance before the
configuration step to create a build sub-directory and a symbolic link
to the configure script. The common gcc.mk had a
HOST_GCC_CONFIGURE_SYMLINK already used by the gcc-initial and
gcc-intermediate steps, but the gcc-final step wasn't using it.

This commit fixes this inconsistency, and therefore removes the
HOST_GCC_FINAL_CONFIGURE_SYMLINK macro.

cd04552e89 gcc: fix Objective-C support
This commit fixes the Objective-C support in the gcc package by making
sure that the runtime Objective-C library is properly installed to the
target.

It also takes this opportunity to slightly reword the Config.in option
help text to have a more meaningful explanation.

Finally, it fixes the gcc-final.mk code to use the correct
BR2_INSTALL_OBJC option rather than the non-existing
BR2_GCC_CROSS_OBJC option, to decide whether Objective-C support
should be enabled or not in the cross-compiler.

69a534b2aa gcc: fix Fortran support
This commit fixes the Fortran support in the gcc package by making
sure that the runtime Fortran library is properly installed to the
target.

It also takes this opportunity to slightly reword the Config.in option
help text, to no longer mention gcc < 4.2 since they are no longer
supported in Buildroot, and to have a more meaningful explanation.

Finally, it fixes the gcc-final.mk code to use the correct
BR2_INSTALL_FORTRAN option rather than the non-existing
BR2_GCC_CROSS_FORTRAN option, to decide whether Fortran support should
be enabled or not in the cross-compiler.

2babed4a50 toolchain-internal: skip gcc-intermediate when possible
When NPTL support was introduced, gcc required a three stages build
process. Since gcc 4.7, this is no longer necessary, and it is
possible to get back to a two stages build process. This patch takes
advantage of this, by doing a two stages build process when possible.

We introduce a few hidden kconfig options:

 * BR2_GCC_VERSION_NEEDS_THREE_STAGE_BUILD, which is set by the gcc
   Config.in logic to indicate that the compiler might need a three
   stages build. Currently, all versions prior to 4.7.x are selecting
   this kconfig option.

 * BR2_TOOLCHAIN_LIBC_NEEDS_THREE_STAGE_BUILD, which indicates whether
   the C library might need a three stages build. This is the case for
   eglibc, and uClibc when NPTL is enabled.

 * BR2_TOOLCHAIN_NEEDS_THREE_STAGE_BUILD finally is enabled when both
   of the previous options are enabled. It indicates that a three
   stages build is actually needed.

In addition to those options, the uClibc/gcc build logic is changed to
use only a two stages build process when possible.

4fc45ccca5 toolchain/gcc: add elf2flt to dependencies
Add host-elf2flt to the gcc common dependencies so we get it built after
binutils but before gcc/uclibc since it's required for all packages and
in some uClibc configuration scenarios.

741cbccb74 Fix build reproducibility in Make 3.82
Make 3.82 no longer sort the result of wildcards (see
http://comments.gmane.org/gmane.comp.gnu.make.bugs/4260). This may break
build reproducibility.

This patch sort results of wildcards to ensure reproducibility.
