[Bug target/21760] New: Powerpc atomic builtins missing PPC405 errata

[pcarlini at suse dot de]

In libstdc++-v3, atomicity.h for powerpc used to include:

#ifdef __PPC405__
#define _STWCX "sync \n\tstwcx. "
#else
#define _STWCX "stwcx. "
#endif

This work around is still missing from the powerpc implementation of the
builtins for atomic memory operations.
