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>
