Note that we do a run-time test of make(1) ['upgrade_checks' target]
to decide if we need to build a bootstrap version.  How hard would
it be to do that for yacc/lex?

/usr/src/Makefile:

# Make sure we have an up-to-date make(1). Only world and buildworld
# should do this as those are the initial targets used for upgrades.
# The user can define ALWAYS_CHECK_MAKE to have this check performed
# for all targets.
#
.if defined(ALWAYS_CHECK_MAKE)
${TGTS}: upgrade_checks
.else
buildworld: upgrade_checks
.endif

# Perform a few tests to determine if the installed tools are adequate
# for building the world.
#
upgrade_checks:
	@if ! (cd ${.CURDIR}/tools/build/make_check && \
	    PATH=${PATH} ${BINMAKE} obj >/dev/null 2>&1 && \
	    PATH=${PATH} ${BINMAKE} >/dev/null 2>&1); \
	then \
	    (cd ${.CURDIR} && ${MAKE} make); \
	fi
