Xtensa port maintainer

[Gerald Pfeifer]

Hi Sterling,

one thing I also recommend is sending regular test results to the
gcc-testresults list.  I believe there were ~two sent in November,
none in December, and one this year so far which is a bit on the
low end.  Several of us operate nightly or at least weekly testers,
and regular testing and sharing of results is certainly something 
that will both help you as a maintainer and others, and in fact I
have seen people help with a port just from seeing test failures.
