Subject: [PATCH] Make it so we can tell configure which cflags utils are built
with
This lets us have kernel.img be built with TARGET_CFLAGS but grub-mkimage and
friends built with HOST_CFLAGS. That in turn lets us build with an ARM compiler
that only has hard-float ABI versions of crt*.o and libgcc*, but still use soft
float for grub.efi.
