build: only require bison and flex if the generated files do not exist
automake recommends including the files generated by bison and flex in
distribution tar-balls and runs bison and flex during `make dist` to
generate them. Thus, in the normal case where the software is being
compiled by an end-user, the generated files already exist and bison and
flex are not required. Therefore, amend the configure script only to
require them if the generated files do not exist.
