Only declare __sigpause in installed signal.h when necessary.
This patch makes the installed signal.h declare __sigpause only when necessary (when a macro definition of sigpause makes use of __sigpause), rather than unconditionally. This fixes false positives in the linknamespace tests by making it visible to those tests that no use of ISO C functionality will actually bring in the definition of __sigpause and so bring in the other symbols defined in the same object. There is no bug filed in Bugzilla because this is fixing false positives rather than any user-visible bug. Tested for x86_64 (testsuite, and that installed stripped shared libraries are unchanged by this patch). * signal/signal.h (__sigpause): Only declare if [__USE_XOPEN && !__GNUC__]. * include/signal.h (__sigpause): Move declaration above call to libc_hidden_proto. * conform/Makefile (test-xfail-ISO/signal.h/linknamespace): Remove variable. (test-xfail-ISO99/signal.h/linknamespace): Likewise. (test-xfail-ISO11/signal.h/linknamespace): Likewise.
