This builds the nptl test:

make subdirs=nptl run-built-tests=no

To run a single test, use this:

bash -x testrun.sh nptl/tst-robustpi8

This is required because the test might not be compatible with the
installed glibc (some nptl tests are whitebox tests).  You can feed the
command line printed due to “bash -x” into strace or a debugger.  The
environment variable settings aren't necessary for most tests.

Thanks,
Florian
