Actually, it shouldn't impact anyone unless they set the variable 
$program_transform_name, e.g., in site.exp (ideally, automatically by 
gcc --  I have another patch for this).  So, there shouldn't be any 
regression issues.

I expect this hasn't been noticed before because the 
program-transform-name used by gcc probably matches the target-alias 
for many cross-compilation environments.  Of course, this is just 
speculation on my part, but it is the only way that the scripts appear 
to work for transformed names.
