Hmm, that's not good.

I guess we need to recursively check for .la files in dependency_libs
and substitute the actual library to link against, plus the contents of
the .la file's dependency_libs.  That's a bit fiddly though...

We might be able to get away with just dropping libstdc++.la, since
linking C++ code should pull it in anyway.  I can't see any other
.la files making it in there unless we start depending on other
libraries.

Anyway, I'll take a look.

If you're using libtool, then xapian-config --ltlibs should be used
instead (which happens automatically if you use XO_LIB_XAPIAN in
configure.in/configure.ac and use AC_PROG_LIBTOOL or AM_PROG_LIBTOOL).
