         pkgsrc/mk/tools: tools.Darwin.mk

Log Message:
Do not use GNU m4 shipped with the OS on systems prior to Mac OS 10.5.
10.4 shipped with gm4 1.4.2, 10.3 came with 1.4.
This is not recent enough for some packages (specifically devel/
autoconf),
so use pkgsrc's gm4 instead.
Fixes PR#40329.

Log Message:
Bump PKGREVISION because the path to m4 was changed on Darwin<9.

The tools framework changed m4 on Darwin<9 from the native one to the
pkgsrc version last month.  bison needs a PKGREVISION bump because it
embeds the path to m4 in its binary.
