Thanks for the report.
Next time, please tell us about your system,
because I didn't 'see any such problem on a rawhide-based build.
However, I did reproduce it on a Debian/unstable system.
I think what's going on here is some linker fun with libtool / pkgconfig
On Fedora it appears we end up automatically linked against pthread.so
as a result of libxml2 (or some othe lib) being linked against it. I
expect that Debian isn't doing this implicit linkage for us. In any
case we should rely on Fedora behaviour, so this patch looks reasonable
to me.
