 #!CommitTicketReference repository="integer-gmp"
 revision="d7bff4dddfa10389156ca11f75a5a23e78cf3ab0"
 Fix GMP v4 compatibility.

 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 might have outdated GMP versions (which I believe is the cause for #8666.)
