Fix x86_64 memrchr namespace (bug 17719).
On x86_64, memrchr (not a standard function) is defined as a strong symbol, instead of a weak alias of __memrchr as on other architectures. This results in linknamespace test failures from the use of __memrchr from dirname. (Not a conformance issue because of the mem* reservation, but contrary to glibc conventions.) This patch makes x86_64 follow other architectures by defining memrchr as a weak alias. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). [BZ #17719] * sysdeps/x86_64/memrchr.S (memrchr): Rename to __memrchr and define as weak alias of __memrchr. (__memrchr): Do not define as strong alias of memrchr. * conform/Makefile (test-xfail-XPG4/libgen.h/linknamespace): Remove variable. (test-xfail-UNIX98/libgen.h/linknamespace): Likewise. (test-xfail-XOPEN2K/libgen.h/linknamespace): Likewise. (test-xfail-XOPEN2K8/libgen.h/linknamespace): Likewise.
