Patch for libstdc++-v3 cut and paste error

[Steve Ellcey]

I am getting duplicate __Atomicity_lock's on hppa due to what is
probably a cut and paste error in config/cpu/hppa/atomicity.h.  The
macro around __Atomicity_lock was changed from
_GLIBCPP_INST_ATOMICITY_LOCK to _GLIBCXX_INST_GLIBCXX_ATOMICITY_LOCK but
int misc-inst.cc it was changed from _GLIBCPP_INST_ATOMICITY_LOCK to
_GLIBCXX_INST_ATOMICITY_LOCK.

Since _GLIBCXX_INST_ATOMICITY_LOCK makes more sense, here is a patch to
change config/cpu/hppa/atomicity.h to match misc-inst.cc.

OK to check in?
