New system for building kernel's config programs
From: Trent Piepho <xyzzy@speakeasy.org>
Since v4l-dvb now uses the kernel's config system, it needs certain kernel
binaries like qconf, mconf, and lxdialog to run the config targets. The
kernel's Makefile is not kind enough to give us a target to just build these
programs. What this patch does is introduce a new makefile,
Makefile.kernel, which includes the kernel's top-level Makefile. Then adds
some new "v4l-*" targets which just build the kernel config programs.
The main v4l Makefile is patched to add the necessary kernel conf programs
as dependencies to their respective config targets. Rules to build the
kernel conf programs are added which invoke a sub-make with the new
Makefile.kernel. These rules are only invoked when the kernel conf programs
needed don't yet exist. If they already exist, no write access to the
kernel source tree is needed.
