  From: Simon Glass <sjg@chromium.org>

Now that the required pieces are in place, add the test program into the
build. Provide the linker script too.

The library requires CONFIG_CMDLINE, at least initially, so don't
attempt to build it when there is no command line.

For clang, an error is produced, so disable it in that case too:

   test/ulib/ulib_test.o: file not recognized: file format not recognized

For now the program just crashes on startup, due to mon_len being larger
than available RAM.
