lang/gawk: backport upstream patch for systems without MPFR and GMPHEADmain

This affects us because MPFR option for multiple-precision floating
-point support added with r322035 (now commit 6c3d62a0a143) back in
2013 is disabled by default.  We might flip the switch one day, but
that would require extra care and testing to not break other things.

Pull the identical patch from GitHub mirror which is easier to work
against than Savannah repository (commit hashes remain the same).
