configure: Make NPTL non-optional
Now all linux-user targets support building with NPTL, we can make it mandatory. This is a good idea because: * NPTL is no longer new and experimental; it is completely standard * in practice, linux-user without NPTL is nearly useless for binaries built against non-ancient glibc * it allows us to delete the rather untested code for handling the non-NPTL configuration Note that this patch leaves the CONFIG_USE_NPTL ifdefs in the bsd-user codebase alone. This makes no change for bsd-user, since our configure test for NPTL had a "#include <linux/futex.h>" which means bsd-user would never have been compiled with CONFIG_USE_NPTL defined, and it still is not.
