I've built for MBX with almost the same, only binutils 2.9.5 instead
of 2.10.

Looking at
  http://lxr.linux.no/source/arch/ppc/kernel/head.S
the problem is apparent:

  255 #ifndef CONFIG_8xx
  256         bl      prom_init
  257         .globl  __secondary_start
  258 __secondary_start:
  ...

  1293 #ifndef CONFIG_8xx
  ..
  1822 #else  /* CONFIG_8xx */
  1823         .globl  giveup_fpu
  1824 giveup_fpu:
  1825         blr
  1826 #endif /* CONFIG_8xx */
  1827
  1828 mmu_off:
  1829         addi    r4, r3, __secondary_start - _start
  1830         mfmsr   r3

__secondary_start is not defined for CONFIG_8xx.  It looks like
head.S changed a bit since 2.2.14, and I wouldn't know which way to go
about fixing it, but I might suggest either backing down to 2.2.14 or
jumping to 2.4.0-test2.

The latest Monta Vista CDK (1.2) appears to include both, and last I
tried their stuff worked quite well with little headaches - I'd recommend
giving it a try,
