<pre style='white-space:pre-wrap;width:81ex'>[10407] Add -o <outfile> option to genrevision.

This gives more flexibility to build systems that don't run genrevision with desired destination as working dir.
For example a build system may run:
build/tools/genrevision -o build/src/shared/revision.h</pre>
