gcc: update to allow compiling different versions

Browse Source 
This is based on the toolchain GCC, and aims to share as much of its
Makefile and patches with that definition. The package requires two
additional patches:

(1) 003-dont-choke-when-building-32bit-on-64bit.patch, which fixes the
`error: size of array 'test_real_width' is negative` error that occurs
when building a 32-bit GCC on a 64-bit host. (Search the Internet for
examples of this error appearing.)

(2) 980-add-nostdinc++.patch, which backports a fix from 11.3.0 (11.2.0
only).

Subject: [PATCH] gotools: fix compilation when making cross compiler
libgo is "the runtime support library for the Go programming language.
This library is intended for use with the Go frontend."
gccgo will link target files with libgo.so which depends on libgcc_s.so.1, but
the linker will complain that it cannot find it. That's because shared libgcc
is not present in the install directory yet. libgo.so was made without problem
because gcc will emit -lgcc_s when compiled with -shared option. When gotools
were being made, it was supplied with -static-libgcc thus no link option was
provided. Check LIBGO in gcc/go/gcc-spec.c for how gccgo make a builtin spec
for linking with libgo.so
- GccgoCrossCompilation, https://github.com/golang/go/wiki/GccgoCrossCompilation
- Cross-building instructions, http://www.eglibc.org/archives/patches/msg00078.html
When 3-pass GCC compilation is used, shared libgcc runtime libraries will be
available after gcc pass2 completed and will meet the gotools link requirement
at gcc pass3
