Looking at ^/head/Makefile@r35703, `make bootstrap` for =
usr.bin/lex/Makefile@r35703 was broken when bootstrap-tools, etc, was =
written.
Here=E2=80=99s the revision where it was brought in:

Finish the import and merge in FreeBSD specific changes.
Add a 'bootstrap' target which *must* be run before building the new
version, since the new scanner relies on the current version of flex to
build itself otherwise.
Here=E2=80=99s what ^/head/Makefile@r35703 used to look like:
33133 adam .if !defined(NOTOOLS)
17308 peter @echo
17308 peter @echo =
"--------------------------------------------------------------"
27910 asami @echo " Rebuilding bootstrap tools"
17308 peter @echo =
"--------------------------------------------------------------"
27910 asami cd ${.CURDIR} && ${BMAKE} bootstrap
...
17308 peter bootstrap:
27910 asami .if defined(DESTDIR)
27910 asami rm -f ${DESTDIR}/usr/src/sys
27910 asami ln -s ${.CURDIR}/sys ${DESTDIR}/usr/src
27910 asami cd ${.CURDIR}/include && find -dx . | cpio -dump =
