make check stderr?

[Mike Mestnik]

I have two questions, the first is about stderr output of tests,
sometimes I like to run under strace to see why the test is failing.
I can't seem to find where stderr is being redirected. I thought it
was in [1]tap-driver.sh so I patched it but still no [2]strace output.
I want to do this under make for travis-ci, so the test can run under
a controlled and known environment.

The other question I had was about overriding check.am, is there a way
to include a replacement copy of this file in my project to enable
extended support for TAP?  I want to have the summery include stats
from TAPs tests and plans.
