Not with the current version of Automake, sorry.  I recommend that you
document the Lex requirement for your users, and only require your users
to have Lex if there is no other way.

If you like, you can file an enhancement bug on the bug-automake list
that allows for this; please include a rationale, so we can judge
importance of this feature.  I'm not sure if automake should detect non
distribution from scanning CLEANFILES.  Stefano is more into the lex and
yacc business ATM, he might have some input on this.
