Doxygen is noisy and can't be asked to be less verbose, but
hiding all output from it to a log file hides any real issues
it is facing.
Redirect only stdout which is where doxygen writes progress
noise, let warnings and such output to stderr stay visible.
Also follow makefile conventions by adding standard make
targets and using DESTDIR macro only in install rule.

The Makefile explicitly assigns file ownership to root. There is a rpm
build time patch to change this while it should not be needed even for
the debian builds.
Apply the patch to code tree and remove the patch file.
