On FreeBSD, "find" does not support the "printf" flag, so we need to
use "gfind" from the "findutils" package.
Fixes: 8260f4f98cfe ("mk: use script to generate examples.dox")

It is one more dependency.
Shouldn't we avoid it by rewritting the shell commands with loops?

Probably in the longer term, yes. If I get the chance, I'll try and rewrite
this script, but let's keep this patch in the queue in case I don't get to
in the 21.11 timeframe.

OK
I can help with the shell tricks if needed.

Well, I was actually considering a rewrite in python for two reasons:
* easy FS scans using the "walk()" function
* portability across OS's [which is the main reason for the work after all]

Applied this patch for 21.11.

Following up on this thread, implemented an alternative fix for this issue
which does not use the extra findutils dependency[1]. I didn't rewrite the
script in python as was my original intent, but used basic shell commands
to work around the lack of printf support in find, leading to a simpler
fix.
