Do not special-case XEN and always use the proper selectors for %fs and %gs
in buildcontext() and setregs(). The consequence was that signal handlers
would have the wrong %fs/%gs. Found by running atf tests under Xen/i386.

Add a missing period.
Add sanity checks for live-image and install-image targets
(which require mtree spec files built with MKUNPRIVED=yes)
to avoid unexpected makefs(8) error during image builds:
 - if release op is specified with live-image or install-image
   at the same time, make sure -U is also specified for the image builds
 - before perform live-image and install-image ops check METALOG file
   in DESTDIR to see if the build have been performed with MKUNPRIVED
XXX: Probably toolchain should create consistent spec files in
XXX: DESTDIR/etc/mtree dir regardless of MKUNPRIVED settings.

to work.
