That does get rid of the binary burp, but 'xargs gzip -f' has been in
the Makefile since January, and gzipping '\n' just started recently.
So what's changed?
It looks like, for whatever reason, make installmandocs always ends up
rerunning mandocs -- there's now a 'GEN Documentation
Docbook//v4l2.xml' printed, and that extra mandocs invocation is where
the problematic second invocation of find is coming from. I won't
pretend to understand the Makefile flow to guess at why that's
happening, but obviously 'make mandocs; make installmandocs' shouldn't
need to regenerate things already generated.
In any event,
