Nope, my bad, it's actually the other way around. From bitbake.conf:
export LDFLAGS = "${TARGET_LDFLAGS}"
So, appending to TARGET_CC_ARCH is the simplest way to pass flags, as that's
embedded into $CC
Another option would have been to call make with -e flag to let environment
variables override the ones in the Makefile, but that's less controlled...
