    there is most likely nothing to bisect, `perf' seems to have never
    required any parser before 3.4. The way the rest of the tools
    (especially `kconfig', `genksyms' and `dtc') manage parsers is via
    pre-generated .[ch]_shipped version of the lexer/tokenizer. It's been
    working well for a long time as such. `perf' will certainly have to
    follow the same path.
