Fix strtoll / strtoull namespace for 32-bit (bug 17594).
For 32-bit platforms, strtoll and strtoull are strong symbols in libc, but they are not in ISO C90, and are brought in by references to __strtoll_internal / __strtoull_internal from scanf. (For 64-bit platforms, they are properly weak.) This patch makes them weak for 32-bit (it has a side-effect of making other symbols weak that don't need to be weak, such as strtol, but that's harmless). Tested for x86 (testsuite, and that the disassembly of installed shared libraries is unchanged by the patch). This fixes all 120 unXFAILed FAILs of the new linknamespace tests seen for x86 (in fact, there are now seven XPASSes of those tests for x86 XPASS: conform/POSIX2008/fcntl.h/linknamespace XPASS: conform/UNIX98/libgen.h/linknamespace XPASS: conform/XOPEN2K/fcntl.h/linknamespace XPASS: conform/XOPEN2K/libgen.h/linknamespace XPASS: conform/XOPEN2K8/fcntl.h/linknamespace XPASS: conform/XOPEN2K8/libgen.h/linknamespace XPASS: conform/XPG4/libgen.h/linknamespace so suggesting that the failures seen for those on x86_64 are in some way architecture-specific or 64-bit-specific). [BZ #17594] * stdlib/strtol.c (SYM__): New macro. (SYM__1): Likewise. (__strtol): Likewise. (strtol): Rename to __strtol and define as weak alias of __strtol. Use libc_hidden_weak.
