The Makefile used for bash-ptest can pick up the path to the uninative
loader through BUILD_LDFLAGS. This includes the full path to the
uninative loader, which is not reproducible. Replace it with /bin/false.
It doesn't appear as if these native programs are used in the test
suites and if there are likely to be other problems related to building
them using the BUILD_* flags.
