Added the fix for the failing tests on ppc64le by working around the

libtool wrapper that adds the `lt-` prefix to binaries not yet installed
on the system which causes the (namely the bsdcpio test_basic.c test)
tests to fail since they expect exact error output which cannot be
achieved if the binary name conatins the prefix
