xsysconf: Only fail on error results and errno set
When testing nptl/tst-pthread-attr-affinity-fail fails with: error: xsysconf.c:33: sysconf (83): Cannot allocate memory error: 1 test failures This happens as xsysconf checks the errno after running sysconf. Internally the sysconf request for _SC_NPROCESSORS_CONF on linux allocates memory. But there is a problem, even though malloc succeeds errno is getting set to ENOMEM. POSIX allows successful calls to clobber errno. So xsysconf just checking errno is wrong. Fix xsysconf by only failing if we have an error result and errno is set.
