TLS support [marius@freebsd.org: svn commit: r219534 - in head: contrib/gcc/config/sparc gnu/lib/libgomp gnu/lib/libstdc++ gnu/usr.bin/cc/cc_tools]

[Marius Strobl]

FYI, now that with binutils 2.17.50 we finally have version supporting
Thread Local Storage on sparc64 I've implemented the necessary relocations
in rtld(1) and enabled TLS support in GCC and its use in malloc(3). Given
that meanwhile TLS otherwise became fairly standard I don't expect any
fallout from this. Should it nevertheless break anything please let me
know.
