This is a bug in libfool.  If it is building libraries that depend on
other libraries, it must explicitly link in (well, record dependencies
for) all libraries on which the library it's building depends, and not
assume some other library linked into the unlucky executable that links
the libfool- generated library will *just happen* to properly record a
dependency on libpthread or libc (or libX11, or...).
