    validate: Clean GMP trees
    
    For reasons unknown `validate` passed `NO_CLEAN_GMP=YES` to
    `maintainer-clean`, leaving a stale `gmp.h` which causes the build to
    fail in the event that the uses a tree for validating for two different
    target platforms. This is quite unexpected, don't do it.
