This breaks build without xl:

gmake[2]: Entering directory '/usr/home/novel/code/libvirt/tests'
  CC       vircapstest.o
In file included from vircapstest.c:25:
In file included from ./testutilsxen.h:5:

# include <libxl.h>
          ^
1 error generated.
Makefile:4935: recipe for target 'vircapstest.o' failed

Probably it would be easier to just include "libxl/libxl_capabilities.h" in 
tests/domaincapstest.c directly? Something like this:

diff --git a/tests/domaincapstest.c b/tests/domaincapstest.c
