after fixing one missing shared-lib dependency in the src/x11 Makefiles,
I looked to see what else might be wrong there.  it turns out that
the answer is "plenty".  I put a patch with fixes for everything
that I found wrong at:

	ftp://ftp.netbsd.org/pub/NetBSD/misc/chs/diff.x11lib.6

there were lots more missing shlib dependencies (which I added),
some unnecessary shlib dependencies (which I removed), and the
list of source files for the Mesa library was missing a bunch of stuff.

anyone see any problems with this?
