A little more info. xgcc is calling as like this:

$ /Users/rmann/Desktop/gcc/gcc-4.2.1/arm-elf-build/./gcc/as - 
march=armv5te -mfloat-abi=soft -o crtbegin.o /var/tmp//ccL30WwD.s
/Users/rmann/Desktop/gcc/gcc-4.2.1/arm-elf-build/./gcc/as: line 2:  
exec: -m: invalid option
exec: usage: exec [-cl] [-a name] file [redirection ...]


It seems a stage 1 build doesn't use the binutils as? What did I do  
wrong here?

TIA,
