        src/usr.bin/make: var.c

            varname-dot-make-level.mk

Log Message:
make: ignore attempts to override a read-only global with the same value

Up to NetBSD 9, make passed around the internal variable .MAKE.LEVEL.ENV
via MAKEFLAGS. Allow these old versions of make to coexist with newer
versions of make. See unit-tests/varname-dot-make-level.mk for details.

Fixes PR pkg/59184.
