Subject: [PATCH] UBUNTU: [Packaging] debian/rules: 1-maintainer.mk -- Use
 make's if-else

Use make's built-in if-else conditional rather than the shell's so we
can drop multi-line shell statements and make the code more readable.

While at it, don't purge the 'build' directory at the end of the config
operations. That's a directory used internally by the kernelconfig script
which handles the cleanup.
