[Bug other/39888] New: TLS emutls not linked to automatically on Darwin

[fago at earthlink dot net]

Using thread local storage (e.g. OpenMP ThreadPrivate variables) on Darwin
requires manually linking to TLS emutls, via either -lgcc_s.so.1 or -lgcc_eh

See the threads:
http://gcc.gnu.org/ml/gcc/2008-12/msg00145.html

>From the above threads, this is evidently quite a mess. However, as I was just
bit by this I hoped it useful to have a bug tracking the issue.

I just ran across this with a fresh bootstrap of gcc 4.4.0 on MacOSX 10.5.6
x86_64, configured as: "--program-suffix=-4.4 --enable-languages=c,c++,fortran"

TLS works fine if I manually link to gcc_s.so.1 or gcc_eh as mentioned above.
