I'm not sure why you're setting targ_extra_libpath, but I don't see how it 
makes sense to have only one endianness in targ_extra_libpath in any case.  
I think setting targ_extra_libpath=$targ_extra_emuls as various targets do 
is safe in any case.

That should be tic6x-*-uclinux.

Should be using remote_exec host (with appropriate adjustments for how 
remote_exec arranges its return value) to work with remote host testing.

I don't see any code to generate PASS lines here if the tests pass.  Each 
test should have some unique text that appears after "PASS: " in the .log 
and .sum if the test passes, and after "FAIL: " if it fails.  It looks 
like this code will just fail tests but not pass them.
