I took a look at libstdc++.so use of exchange_and_add on powerpc 32-bit. There
seems to be a lot of places where it appears, even before Benjamin's change,
ie. r184109.
Uses of exchange_and_add common to both r184109 and r186130, the latter patched
with http://gcc.gnu.org/bugzilla/attachment.cgi?id=27094 to get
_GLIBCXX_ATOMIC_BUILTINS enabled on powerpc.

Use of exchange_and_add only in r184109
r186130 with patch appears to neither use exchange_and_add or atomics in these
functions. (I say appears because I only looked for direct calls.)
