Comment (by hvr):

 Replying to [comment:33 rwbarton]:
 > So if we wait for GMP 6.0.1 and then update the in-tree tarball, this
 should get fixed automatically.

 I'd rather get rid of the in-tree GMP tarball altogether than updating it,
 as it will increase the ghc.git history by a 2MiB blob everyone will have
 to download each time `ghc.git` gets cloned. Morever, the work I'm doing
 in #9281 is also somewhat motivated by finally getting rid of the in-tree
 GMP tarball for good.
