Static library exception for flex

[Jason L Tibbitts III <tibbs math uh edu>]

I've agreed to give the merge review of flex
(https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=225758) a once
over, since there was confusion about whether it had been reviewed and
approved.

The package is clean, and given that it's obviously a development-only
package it gets a pass on things like including header files in the
main package.

However, it also includes a static library, libfl.a, which every
flex-using application links against.  And according to our
guidelines, this needs an ack from FESCo.  I can't imagine that we'd
break every flex-using application by changing the way it works, but I
figure it's better to follow proper procedure here.

So, comments?
