Yep, make that part of the libgmp setup. If you switch to automake you
can add that option to a Kconfig in the libgmp directory, again, there
are quite a few examples in the tree. some have their own Kconfig files:
grep -l automake lib/*/makefile user/*/makefile
ls lib/*/Kconfig user/*/Kconfig
to find them all.
