Maybe now it will be more obvious why I thought that upgrade_checks
should always be done, for all standard src/Makefile targets.
Currently, you either need to upgrade your /usr/bin/make binary
manually, or to use this command from /usr/src:
make buildkernel -DALWAYS_CHECK_MAKE ...
with up-to-date tools/regression/usr.bin/make/ and usr.bin/make/
sources.
