GHC Bindist is Broken on FreeBSD/amd64

After correcting the name of the FreeBSD/amd64 platform in PlatformSupportsSharedLibs it turned out that shared libraries do not build on that platform at all. Log shows that the problem is with the integer-gmp library where the sources are not compiled with the -fPIC flag.

Excerpt from the build log:

...

According to Simon Marlow, it looks like it is building the in-tree gmp library rather than using a local one, and perhaps there is no shared version, so gcc picks up the static one and complains. There should be a shared gmp library when shared Haskell libraries are being built.
