Fix getlogin_r namespace (bug 18527).
Various functions in XPG4 bring in references to getlogin_r, which is not in XPG4; this is also a bug for some older POSIX versions which aren't yet covered by the linknamespace tests. This patch fixes this by making getlogin_r into a weak alias for __getlogin_r and using __getlogin_r as needed. Tested for x86_64 and x86 (testsuite, and that disassembly of installed stripped shared libraries is unchanged by the patch). [BZ #18527] * login/getlogin_r.c (getlogin_r): Rename to __getlogin_r and define as weak alias of __getlogin_r. Use libc_hidden_weak. * sysdeps/mach/hurd/getlogin_r.c (getlogin_r): Likewise. * sysdeps/unix/getlogin_r.c (getlogin_r): Likewise. * sysdeps/unix/sysv/linux/getlogin_r.c (getlogin_r): Likewise. * include/unistd.h (__getlogin_r): Declare. Use libc_hidden_proto. * posix/glob.c (glob): Call __getlogin_r instead of getlogin_r. * conform/Makefile (test-xfail-XPG3/glob.h/linknamespace): Remove variable. (test-xfail-XPG3/wordexp.h/linknamespace): Likewise. (test-xfail-XPG4/glob.h/linknamespace): Likewise. (test-xfail-XPG4/wordexp.h/linknamespace): Likewise.
