The ARM EABI + HF isn't well tested (to my knowledge) of oe-core.  I was under 
the impressions a few people did use it, and it was working successfully for 
them.  (Generally speaking people seem to agree that there is a place for ARM 
EABI + HF, but the performance increase to the couple of items where it helps is 
generally not worth the pain of incompatibility with the core ARM EABI.  Thus 
it's not used very much in OE.)

Could you verify that the stock configuration (without any of the changes you 
described above) is working and will boot w/o a kernel panic at init?

If so then it'll be easier to help you track down the particulars of the ld.so 
name change and related items.
