Re: pkg/42926 (m4 doesn't build because an include error)

[Johannes Hofmann <Johannes.Hofmann%gmx.de@localhost>]

Upstream lib/fflush.c now already contains DragonFly specific code,
and m4 compiles and builds just fine without the DFLY-specific
fflush.c.  Also it passes the same tests with and without the patch.

So maybe we could just remove the DFLY-specific fflush like this:
