BeagleBoardAndOpenEmbeddedGit wiki fixed, please don't unfix it

Hi,

I got tired of all the people encountering breakage after following http://elinux.org/index.php?title=BeagleBoardAndOpenEmbeddedGit instead of http://www.angstrom-distribution.org/building-angstrom so I ripped out the duplicate part in the wiki.

Before you all go adding in well intentioned, but wrong info like the good wiki users you are: think twice.

Fight the urge to add things to a wiki just because it's a wiki.

Yes, I'm annoyed,

Koen
