buildgcc: Always set HOSTCFLAGS

Always set HOSTCFLAGS to the flags GMP was built with, defaulting to
    "-Os" if it isn't built yet. Previously, if GMP was already built or
    not even in the list of packages to be built, this was silently skipped
    and other packages were built with empty HOSTCFLAGS.
