I know it's very, very late to respond to this, but I just had an email
conversation with Peter Grehan, where he ran into this problem when
attempting to build -CURRENT on 8.1-RELEASE.  This doesn't have the
followup r214779 yet, where the needed update to lex is merged.

Of course, I also know that building -CURRENT on 8.1-RELEASE is
officially not supported, but if there is a relatively simple fix to
make it work, it should not be a problem to apply, right? :)

The root of the problem is that, even if buildworld is completed, the
"stage 2.3: build tools" (kernel-specific) part of Makefile.inc1 uses
lex and yacc from /usr/bin, *not* the ones built under ${WORLDTMP}
(usually in /usr/obj/usr/src/tmp/legacy/usr/bin).

Therefore, I propose to set PATH to ${BPATH}:${PATH} in this stage, so
the "good" versions of lex and yacc are used.  As per attached diff.

(NOTE: even with this diff applied, doing 'make buildkernel' without
first doing 'make buildworld' or 'make kernel-toolchain' will not work,
because there will be no copy of lex and yacc in /usr/obj.)
