Configured gcc with CFLAGS=-xarch=v9 (among other flags) to produce 64-bit code
from the system compiler, instead of the default of 32-bit.

----(end build log excerpt)----
build/errors.o and build/genmodes are compiled and linked without the original
CFLAGS, while libiberty.a was. From the looks of it, gcc/Makefile doesn't pick
up CFLAGS at all.
