The revision you have does not support the "rev" instruction when using 
-CpARMv6. Use -CpARMv5 (or no switch, as it is the default) to create 
the (cross-)compiler.
That has been fixed in a later revision in trunk.

The generated compiler can then be used to generate ARMv6 code, but of 
course still does not support the assembler "rev" instruction.

I will look at how much work it is to merge the branch to latest.

Note that if you want to try, some time ago android/x86 compiler 
support has been added (must add -Cfsse3 though to get valid 
executables).
