This makes sure to not include gmp.h for building generator programs
on the host (and thus require gmp.h on the host).
Configury might need updating for the use of GENERATOR_FILE
from system.h as well, but the patch below is a strict improvement
over the current situation, restoring previous behavior.
Bootstrapped on x86_64-unknown-linux-gnu.
Ok?
Thanks,
Richard.
