nptlonly was used during the transition from linuxthreads to NPTL in glibc.
 The toolchain would build glibc twice, once with linuxthreads, and the
other with NPTL.  By setting this USE flag, you would cause glibc to only
build the NPTL version, thus cutting the build-time in half.

Whether it's needed or not anymore, I am not certain.  It might be left over
for people who need an upgrade path from such an old glibc to something newer.
