crossgcc: Clean GNU make context so builds succeed

GCC's build system is sometimes confused by our build system's
    configuration: make crossgcc failed, while
    util/crossgcc/buildgcc -p armv7-a-eabi didn't.

Make sure the GCC build system runs independently from
    ours by breaking any ties.
