The libc is somewhat fragile when built with some insane CFLAGS, for
instance (e)glibc is built at O2 (by Thomas P), allowing a switch to
another optimization level might be troublesome.
uClibc forces -Os in Rules.mak for BUILD_CFLAGS for example.
I'm unsure if we'd like to open pandora's box by merging them, maybe add
an option just for the libc?
Regards.
