ACK on the idea, NACK on the implementation.

ANGSTROMLIBC is called ANGSTROMLIBC and not ANGSTROM_LIBC for a reason, 
since you can't pass env vars with underscores throught bitbake: 
http://lists.linuxtogo.org/pipermail/openembedded-devel/2008-December/007258.html

I've shown the PREFERRED_LIBC thing in the past to other OE core 
developers as an example of the mindless copy/paste/rename process in 
angstrom clones. Don't clone if you don't know what you are doing.

So please keep things you want to override in buildscripts (e.g. 
machine, libc, distro) underscore free :)
