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).
