Remove NPTL configure errors based on top-level configure tests.
sysdeps/nptl/configure.ac has code to give errors if certain tests in the top-level configure failed. However, all those failure conditions also produce errors in the top-level configure, so the errors in the NPTL configure are completely redundant; this patch removes them. (As suggested in <https://sourceware.org/ml/libc-alpha/2015-10/msg00510.html>, I think the top-level tests in question can be completely removed as unnecessary given the version tests. But even without that there is clearly no point in duplicating code that gives an error if the test fails.) Tested for x86_64 (testsuite, and that installed shared libraries are unchanged by the patch). * sysdeps/nptl/configure.ac: Do not give errors based on the results of top-level configure tests. * sysdeps/nptl/configure: Regenerated.
