Fix limits.h NL_NMAX namespace (bug 19929).
bits/xopen_lim.h (included by limits.h if __USE_XOPEN) defines NL_NMAX, but this constant was removed in the 2008 edition of POSIX so should not be defined in that case. This patch duly disables that define for __USE_XOPEN2K8. It remains enabled for __USE_GNU to avoid affecting sysconf (_SC_NL_NMAX), the implementation of which uses "#ifdef NL_NMAX". Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). [BZ #19929] * include/bits/xopen_lim.h (NL_NMAX): Do not define if [__USE_XOPEN2K8 && !__USE_GNU]. * conform/Makefile (test-xfail-XOPEN2K8/limits.h/conform): Remove variable.
