To work around thiscyclic dependency we can build a bootstrap version of m4 (with pre-generatedfiles) then use that to build the real m4.This patch also changes the xz/unxz/dd tools to always use the host versionsince the version in the source tree cannot easily be bootstrapped on macOSor Linux.Reviewed By: brooks, imp (earlier version)Differential Revision: https://reviews.freebsd.org/D25992 List of files: /freebsd-14.2/tools/build/bootstrap-m4/Makefile Tue, 25 Aug 2020 13:29:57 +0000 Alex Richardson <arichardson@FreeBSD.org>
