We had started relying on GMP 5.x (for usage of mpz_powm_sec), but this is pretty painful on RHEL-esque targets, which still use GMP 4.x. In the mean time while we're still supporting this, it's easier to just fallback to mpz_powm when _sec is unavailable, and emit a WARNING for using the primitive. This also installs a header, HsIntegerGmp.h, which clients could use for a fallback. As a side note, this will probably also help Debian oldstable users who might have outdated GMP versions (which I believe is the cause for #8666.)
