We run automatic periodic testing and arm-linux is one of the covered
platforms - apologies for not having the GDB test results posted
anywhere, we do send out GCC logs.

Unfortunately annota1.exp does not run for cross testing, probably
because it relies on mixed GDB and inferior output.  And a binutils
bug caused the results to be garbage for a couple of months.  Which
means that I have before results, but not after; I'll keep an eye out
for the next batch.
