Work around Solaris ld bug linking __tls_get_addr on 64-bit x86
* m4/druntime/os.m4 (DRUNTIME_OS_LINK_SPEC): New macro.
* configure.ac: Call it.
* configure: Regenerate.
* Makefile.in, libdruntime/Makefile.in, src/Makefile.in,
testsuite/Makefile.in: Regenerate.
* src/libgphobos.spec.in (*link): Append OS_LINK_SPEC.
