I have a questions:

* Were you able to produce a *bootable* kernel after your workarounds?

* What did your make invocation look like?

The reason I ask it that you are using a compiler that defaults to 
little-endian and 32-bit.  Unless you did something to override these 
defaults, I would be surprised if you obtained something bootable.
