    Do not export variables to GRUB build
    
    Variables in coreboot and not in line with GRUB ones. E.g. HOSTCC is both
    HOST_CC and BUILD_CC for GRUB (consult INSTALL for more details) and
    what coreboot calls CC is TARGET_CC for GRUB.
    
    Current code plugs this by defining variables explicitly but it has a nasty
    effect that make stops caring about flags added in makefile itself. Undef
    as many variables as possible but still pass them to configure for them to
    have correct effect and keep CC assignment as my make version doesn't undefine
    it even when instructed to do so.
    
    Tested with qemu.
