[PATCH 18/20] coreboot/fam15h: fix binutils build error on gcc13

[Leah Rowe]

From: Leah Rowe <leah@libreboot.org>

newer gcc treats warnings as errors by default. a user on gnuboot
irc had issues compiling kgpe-d16 images on current gentoo as
of 13 january 2024. the kgpe-d16 boards use coreboot 4.11_branch,
on which coreboot's crossgcc toolchain uses binutils 2.32.

instead of endlessly patching binutils, modify coreboot's build
system to disable warnings-as-errors when building binutils.

with this patch, it will now be possible to compile images for
kgpe-d16, kcma-d8 and kfsn4-dre mainboards on modern distros.

+Subject: [PATCH 1/1] buildgcc: don't treat binutil warnings as errors
+
+binutils 2.32 has too many build warnings on modern toolchains,
+and newer gcc versions are much more pedantic about warnings,
+treating them as errors by default.
+
+instead of patching binutils like before, just let the warnings
+persist. the warnings are benign. a user on gnuboot irc had serious
+issues building binutils 2.32 specifically, on current gentoo as
+of 13 January 2024. this patch mitigates those warning messages.
