Fix ISO C threads installed header and HURD assumption
Set installed NPTL header as the expected one (instead of an internal one for glibc testsuite) and add a hurd specific stdc-predef with __STDC_NO_THREADS__. Checked on both i686-linux-gnu and i686-gnu that both threads.h and stdc-predef.h are the expected ones. * nptl/threads.h: Move to ... * sysdeps/nptl/threads.h: ... here. * sysdeps/hurd/stdc-predef.h: New file.
