Hi,

I'm interested in building the cross toolchain needed to build carl9170 
wireless firmware. The docs say that it needs an SH-2 toolchain, but the build 
scripts only use the 'sh-elf' tuple. (I've asked about this on the linux-
wireless list but haven't garnered a response.)

It seems like config.sub is equally happy to accept sh-elf and sh[1234]-elf, so 
I wonder if the first is an alias and to what, or how Binutils+GCC interprets 
the difference.

Thanks,
John
