Well, the parallel build doesn't work as there are not

set correctly. When running 'make -j' I see this error:
make[2]: Entering directory '/home/zippy/work/libvirt/libvirt.git/src'

The fix is to correctly set dependencies by letting make know that .c
and .h are to be generated from .l. Moreover, the section is moved
closer to the other section which uses it.

This is reworked version of my first patch. The difference is
that I'm using a stamp this time.

The build works with this patch, however there is still mysterious
src/.h and src/lex.xl_disk_.c files which are copies of
src/xenconfig/xen_xl_disk.h and src/xenconfig/xen_xl_disk.c only with
different file names inside.
