commit e9e7c496b0b346f79f38035d0e7805fc80eb3e67

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.
