My reason for using the xscale-* triplets was because of the warning below from

# The iWMMXt multilibs are suppressed for now because gcc only
# supports generating them with the IWMMXT or AAPCS ABIs, neither of
# which is the default.  Until GCC can generate code for an iWMMXt  
# which will work with the default ABI it is not possible to safely 
# generate these multilibs.

Since I'm not going to be using the default ABI I thought I would be better off
adding a specific target since my aim is to produce a complete Linux
environment for general use rather than a stand-alone project.  That way I
could enable the iWMMXt multilibs without worrying about incompatibility with
non iWMMXt targets.  Perhaps I'd be better off using iwmmxt-*?
