package/gcc: remove gcc 4.9

In order to reduce the number of choice in gcc selection, remove the
gcc 4.9 version.

This version was kept due to libstdc++ ABI-incompatible changes and
other build issues with kernel and bootloader as reported by Arnout
[1].

Since then, gcc 4.9 is not supported any more since glibc 2.29 [2]
and recent kernel and bootloaders has been fixed to use more recent
compiler version.

-Allow C99-depending features of libstdc++ with uClibc
-
-The libstdc++ code is fairly restrictive on how it checks for C99
-compatibility: it requires *complete* C99 support to enable certain
-features. For example, uClibc provides a good number of C99 features,
-but not C99 complex number support. For this reason, libstdc++
-completely disables many the standard C++ methods that can in fact
-work because uClibc provides the necessary functions.
-
-This patch is similar and highly inspired from
-https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58393, but implemented in
-a way that doesn't involve changing the configure.ac script, as
-autoreconfiguring gcc is complicated. It simply relies on the fact
-that uClibc defines the __UCLIBC__ definition.

-[PATCH] cilk: fix build without wchar
-
-When building against uClibc with wchar support disabled, WCHAR_MIN and
-WCHAR_MAX are not defined leading to compilation errors.
-
-Fix it by only including the wchar code if available.

-Subject: [PATCH] xtensa: add -mauto-litpools option
-
-With support from assembler this option allows compiling huge functions,
-where single literal pool at the beginning of a function may not be
-reachable by L32R instructions at its end.
-
-Currently assembler --auto-litpools option cannot deal with literals
-used from multiple locations separated by more than 256 KBytes of code.
-Don't turn constants into literals, instead use MOVI instruction to load
-them into registers and let the assembler turn them into literals as
-necessary.
-
-2015-08-12  Max Filippov  <jcmvbkbc@gmail.com>
-gcc/
-	* config/xtensa/constraints.md (define_constraint "Y"): New
-	constraint.
-	* config/xtensa/elf.h (ASM_SPEC): Add m(no-)auto-litpools.
-	* config/xtensa/linux.h (ASM_SPEC): Likewise.
-	* config/xtensa/predicates.md (move_operand): Match constants
-	and symbols in the presence of TARGET_AUTO_LITPOOLS.
-	* config/xtensa/xtensa.c (xtensa_valid_move): Don't allow
-	immediate references to TLS data.
-	(xtensa_emit_move_sequence): Don't force constants to memory in
-	the presence of TARGET_AUTO_LITPOOLS.
-	(print_operand): Add 'y' format, same as default, but capable of
-	printing SF mode constants as well.
-	* config/xtensa/xtensa.md (movsi_internal, movhi_internal)
-	(movsf_internal): Add movi pattern that loads literal.
-	(movsf, movdf): Don't force constants to memory in the presence
-	of TARGET_AUTO_LITPOOLS.
-	(movdf_internal): Add 'Y' constraint.
-	* config/xtensa/xtensa.opt (mauto-litpools): New option.

-Subject: [PATCH 3/3] xtensa: fix _Unwind_GetCFA
-
-Returning context->cfa in _Unwind_GetCFA makes CFA point one stack frame
-higher than what was actually used by code at context->ra. This results
-in invalid CFA value in signal frames and premature unwinding completion
-in forced unwinding used by uClibc NPTL thread cancellation.
-Returning context->sp from _Unwind_GetCFA makes all CFA values valid and
-matching code that used them.

-Add musl support to gcc
-
-This patch comes from the musl-cross project at
-https://bitbucket.org/GregorR/musl-cross/src. Compared to the upstream version:
-
- * the config.sub modifications have been removed, because Buildroot
-   already overwrites all config.sub with a more recent config.sub
-   that has musl support.
-
- * change to ensure that a dummy dynamic linker path
-   MUSL_DYNAMIC_LINKER<foo> is defined for all architectures,
-   otherwise building gcc for architectures not supported by musl was
-   causing build failure. Bug reported upstream at
-   https://bitbucket.org/GregorR/musl-gcc-patches/issue/4/musl-gcc-patches-break-the-build-on.
-
- * change the USE_PT_GNU_EH_FRAME logic to keep the existing gcc logic
-   and only add the musl one as an addition, not as a replacement. Not
-   doing this breaks C++ exception handling with glibc, because
-   USE_PT_GNU_EH_FRAME doesn't get defined due to the configure script
-   not testing dl_iterate_phdr() on any system except Solaris.

-This has been verified to apply to at least 4.9.4 and up to 5.4,

-Subject: [PATCH] Use ucontext_t not struct ucontext in linux-unwind.h files.
-
-Current glibc no longer gives the ucontext_t type the tag struct
-ucontext, to conform with POSIX namespace rules.  This requires
-various linux-unwind.h files in libgcc, that were previously using
-struct ucontext, to be fixed to use ucontext_t instead.  This is
-similar to the removal of the struct siginfo tag from siginfo_t some
-years ago.
-
-This patch changes those files to use ucontext_t instead.  As the
-standard name that should be unconditionally safe, so this is not
-restricted to architectures supported by glibc, or conditioned on the
-glibc version.
-
-Tested compilation together with current glibc with glibc's
-build-many-glibcs.py.
