Configure GMP and Mingw32

The following lines are in fptools/ghc/rts/Makefile. 
They handle configure'ing GMP, but contrary to what
the comment indicates these lines *cause* problems
when I'm building for mingw32 from cygwin.  I have to
edit the makefile so that the first branch (the one
that passes 'host') is taken instead of the second
branch (the one that passes 'target').  Does someone
know of a specific situation in which these lines are
needed?  If not I think it might be best to just use
the one brance and make sure to pass through *all* of
build, host, and target.

# Compile GMP only if we don't have it already
# We use GMP's own configuration stuff, because it's
all rather hairy
# and not worth re-implementing in our Makefile

ifneq "$(HaveLibGmp)" "YES"
ifneq "$(HaveFrameworkHaskellSupport)" "YES"
ifneq "$(HOSTPLATFORM)" "i386-unknown-mingw32"
boot ::
	cd gmp && ./configure --enable-shared=no \
		--host=`echo $(HOSTPLATFORM) | sed
# Pass --target to configure of GMP, so that building
for mingwin under
# cygwin works properly (when the host is not the same
as the target)
boot ::
	cd gmp && CC=$(WhatGccIsCalled) ./configure
--enable-shared=no --target=$(HOSTPLATFORM)
