Comment (by snowleopard):

 Thank you for the patch! Glad you made it work with `--integer-simple`.

 It's difficult to figure out what's wrong with `libgmp` on FreeBSD from my
 Windows machine, but I can point you to the GMP-related build rule:

 https://github.com/ghc/ghc/blob/94756201349685a34c4495addd3484fdfcc8b498/hadrian/src/Rules/Gmp.hs#L46

 Also, you could try to build GHC using in-tree GMP. I think the easiest
 way to do that is to comment out these lines:

 https://github.com/ghc/ghc/blob/94756201349685a34c4495addd3484fdfcc8b498/hadrian/src/Rules/Gmp.hs#L51-L58
