Recent ld warns about libxenlight.so's dependency libraries not being
available, which can be easily avoided by not just passing the raw
library name on ld's command line.
In the course of checking how things fit together (I originally
suspected the warning to come from the linking of xl) I also noticed a
stray L in SHLIB_libxenguest, which gets removed at once.

Heh, I wonder how this ever worked, but it turns out SHLIB_libxenguest
is not used in tree.

This looks correct to me.

Looks like I (unwittingly) fixed this aspect in
http://lists.xen.org/archives/html/xen-devel/2015-10/msg02256.html
too. I can easily rebase.
Since you have a pickier ld than me I wonder if you would mind trying my patch out on top of yours too?

Actually, no I didn't.
