It appears that our Makefile is passing the wrong target into the GMP
configure.  We'll fix this, but in the meantime, you could either:

	- remove the --target=$(HOSTPLATFORM) from ghc/rts/Makefile,
	  to let GMP figure out its own target, or

	- install GMP yourself, so the GHC build system will detect that
        you have it installed and not attempt to build its own version.

Thanks for the report.
