The -L/usr/xen42/lib is for yajl, the problem was that it was missing
libxenlight.so, so it could not link to the proper functions (or it
was trying to use the old library from /usr/xen42/lib instead of the
new one). I've modified a patch in your series to include
libxenligh.so when compiling xl.

Now I have a similar problem, and I think it's because Xen is trying
to use the old header files and libraries in /usr/xen42/ instead of
the new ones.
