[PATCH] doc/api: remove dependency on findutils on FreeBSD

[Thomas Monjalon]

22/12/2021 16:18, Bruce Richardson:
> Standard "find" on BSD does not support the "-printf" so gfind from
> findutils package was used to enable full doc builds. We can remove this
> extra dependency by using "sed" and "tr" to adjust the output from
> regular find instread.

> Fixes: 8260f4f98cfe ("mk: use script to generate examples.dox")
> Fixes: 499fe9dfcfc7 ("doc: add dependency on examples for API doxygen")
> Fixes: 897e55c8d27f ("doc: fix Doxygen examples build on FreeBSD")

Broke up this long line (after each pipe),
and applied, thanks.
