Subject: classes, conf: Exclude native and nativesdk recipes from libc specific
	override
Date: Thu, 01 Dec 2011 03:07:07 -0000

Based on suggestions from RP

libc-uclibc and libc-glibc overrides are for denoting
system C library in use on the target and not for the
host therefore we make sure that the override only takes
effect for target recipes only.
