[for 0.1 release 01/11] crossgcc/default: fix build errors on host gcc 13.x

[Leah Rowe]

From: Leah Rowe <leah@libreboot.org>

import a workaround from upstream for gnat builds, and
disable treating warnings as errors. i've pretty much
taken the bazooka approach here.

tested on a bleeding edge gnu+linux distro. boards
using coreboot/default should now compile on parabola,
for example.
