I redid the test and didn't see a difference, and then I ran a
standalone microbenchmark to compare strcoll() vs strcoll_l(), and
didn't see a difference there, either.

Another implementation may show a difference, but it doesn't seem to be
a problem for glibc.

I think this patch series is a nice cleanup, as well, making libc more
like the other providers and not dependent on global state.
