We may need to special-case amd64 then.

I don't think hppa has working TLS yet.

This is the problem: if modern versions of Berkeley DB are built on a
buildd that supports NPTL, configure will decide to build the libraries
with POSIX mutexes.  Then, when a user running, say, Linux 2.4.16 installs
the libdb package on that arch, it fails to work.  We discussed a long
time ago compiling NPTL-happy instances of libdb and sticking them in
/usr/lib/tls, but not much work has been done on that.
