Do you know why ld.bdf doesn't read ld.so.conf from the chroot?  Perhaps in the
arm case its because ld.so.conf wasn't in the chroot (only ld.so.conf.d which is
normally recursively included by ld.so.conf on ubuntu)?  Does copying ld.so.conf
from /etc to system/etc also fix
this issue?

I don't see ld.bfd or gold reading anything from $sysroot/etc.

OK then this solution seems good to me.  LGTM.

When looking into this problem I found messages from you regarding then back in
2007 :)

http://gcc.gnu.org/ml/gcc/2007-03/msg00082.html

I guess there was no upstream solution to this that landed :(

That's actually not me. Close, but no cigar.

Wow.  What a crazy coincidence.  The problem he is talking about is *exactly*
this problem we have run into right?  Strange indeed :)
