oprofile needs binutils on target, which in turns requires gmp on
target. So the fact that gmp gets compiled is normal.

However, the fact that BR2_PACKAGE_LIBGMP is not set is indeed
incorrect. But Gustavo has a patch series that rewrites how binutils,
gmp, mpfr are handled, so presumably he could fix that particular
problem as part of this patch set.
