[yocto] Pandaboard indeed does not boot on master

[maniacbug]

As discussed in a previous thread (https://lists.yoctoproject.org/pipermail/yocto/2012-July/010540.html), pandaboard images fail to 
boot now.  I also verified this.  Releases after denzil will drop support for pandaboard in the current state.

I filed a bug, 2884 (https://bugzilla.yoctoproject.org/show_bug.cgi?id=2884) against this issue.  It would be great to see 
a fix.  Looks like the suggestion is to use an earlier GCC version for this hardware.
