I'd prefer the following: put libc_r back for now so it's easily
available as a fallback, make libthr the default on sparc64 and alpha
for a few weeks so that I and others can test it, and then flip the
switch once you've fixed any problems that are found with it (in the
past libthr did not work 100% on sparc, but you may have fixed it).
