 I get this error when I run hello world with `ghci` or `runghc`:

 {{{
 $ ghc-stage2 --interactive Hello.hs
 GHCi, version 8.5.20180117: http://www.haskell.org/ghc/  :? for help
 gcc: error: libgmp.so: No such file or directory
 gcc: fatal error: no input files
 compilation terminated.
 `gcc' failed in phase `gcc'. (Exit code: 1)
 }}}

 It works with 8.2.2's `runghc` and `ghci` so it seems like a regression to
 me.

 This also causes validate failure on my laptop, because at one point
 validate script runs `runghc`.

 OS: Xubuntu 16.04.2

 `libgmp.so` location:
