Hadrian: compile libgmp static on Windows
gmp on Windows must always be build statically. We simply can't support dynamic gmp on Windows at the moment.
Fixes the CIs for Hadrian and https://ghc.haskell.org/trac/ghc/ticket/16231
I'm sure this isn't the right way? But I got lost jumping around the code. Mainly I couldn't tell what the relationship of an "Action" is to an Expression. Action doesn't seem to be an instance of e.g. Applicative, so How can I do an || on two Action Bool. Is there any haddock for Hadrian?
