[mc1322x] CodeSourcery , flash loader

[Dean Hall]

Andrew,  I was able to recreate the issue of the CodeSourcery
assembler segfault on start-romvars.s.  I built the CS toolchain
manually on Mac OS X and got this error when building libmc1322x:

Looks like I am going to go build the straight GNU ARM toolchain manually now.
