gcc: update to allow compiling different versions 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). Signed-off-by: W. Michael Petullo <mike@flyn.org> (cherry picked from commit ceaa6e840e0b57c1b47c784997187044e3311d23)
