I'm not familiar with this particular project, but unless it's bare
metal or nearly so like a kernel or bootloader, that's likely not a
good idea, since it won't end up obeying our TARGET_CC_ARCH.  An
alternative to setting CC/AR in EXTRA_OEMAKE or removing those lines
from the makefile would be to set them there, but using ?=.  This
would let the versions in the environment be used in preference to
those.
