I think I agree.
Building the *basic* kernel is different - I want people to be able to
build the kernel and install it and test it out with a fairly minimal
But the perf tools
(a) are mainly useful for developers who can easily install these
things *anyway* (ie we're not talking the same kind of usage cases
where we want to encourage random people off the street to build and
(b) already require things that are *much* less common than flex (ie
the whole libelf-devel stuff etc)
so I think having pre-generated lex/yacc files is just silly - just
install the tool.
