The ABIs are very close so we should be able to converge some of the
infrastructure. For tls.h it depends on a common usage of __thread_self
and the rest should just work. I was waiting to see how PPC32 ended up ...
One thing nags at me. Does PPC32 need to be backward compatible to older
libpthread implementations? If so this would complicate converging
PPC32/PPC64. PPC64's first release is 2.2.5 and so far we don't need any
symver changes to maintain compatibility.
