PATCH: Provide runtime intialization of _STL_mutex_lock class

[Benjamin Kosnik]

John, a couple of things.

1) why are you adding this to libsupc++? it should be added to 
src/Makefile.am

2) there is already a src/globals.cc -- why can't you use that?

3) In general, the naming seems a bit off. stl_globals, yet the patch is 
for threads and mutexes.... also we're trying to go away from _STL bits and 
towad _GLIBCPP_ bits in names.
