The previous gcov behavior was to always output errors on the stderr channel.
This is fine for most uses, but some programs will require stderr to be
silent for certain tests. This change allows configuring the gcov output by
an environment variable which will be used to open the appropriate file.
Why is the invoker unable to direct fd2 before execing gcov?
