From: Anthony G. Basile <blueness@gentoo.org>

This patch addresses three issues to make gradm respect aspects
of a typical gentoo system: 1) We do not strip binaries automatically
to permit FEATURES="nostrip" to work, 2) We respect user provided
CFLAGS and LDFLAGS, 3) We install our udev rules in /lib/udev/rules.d.
