grub: fix builds on non x86_64 build hosts by using TARGET_ for build

Browse Source 
With these changes configure_target no longer complains about no-prefix
on cross compiling. On an aarch64 build host the target_ compile fails
when the build host gcc is used with the -m32 option. On an x86_64 build
host, the host gcc compiles grub (-m32 and assembly) successfully.
