Yeah, I looked further at PHP's configure, and it explicitly filters out
-lc_r and -pthread.  I add a flag to libxml2 to build it without thread
support.  Rebuild libxml2 with -DLIBXML_WITHOUT_THREADS, and you should
be set with PHP.  I wonder if it would be okay to allow -pthread in
mod_php (of course, FreeBSD may prevent -pthread from being linked in to
the final mod_php .so).
