Something has happened to the CFLAGS -- you're missing -D_GNU_SOURCE
which is needed for the definition of CPU_ZERO.
I can get the same behaviour with:
make EXTFLAGS=
but then I got confused looking at the Makefile. I don't understand
how that ever works, since EXTFLAGS is used before it's defined.
