Ah, I see. Angstrom assigns TARGET_VENDOR in conf/distro/include/angstrom.inc 
and I had to change it to a weak assignment in Arago, because distro 
configuration overwrites local.conf configuration. You can try poking the 
correct value either in angstrom.inc or glibc-external.inc for now - need to 
figure out the proper place for it later.

I don't think it matters on that level...
