As noted at 
http://lists.openembedded.org/pipermail/openembedded-core/2014-August/096568.html 
and related messages, raspi configures (or at that time configured) gcc 
to build for armv6 but it's actually armv6zk.  It's entirely possible 
chromium doesn't support armv6 without armv6k features being enabled.  
My best guess is meta-raspberrypi needs to be fixed, which might require 
some enhancements in oe-core's gcc.
