Currently the parsers objects (bison/flex related) are each time perf
is built. No matter the generated files are already in place, the
parser generation is executed every time.
Changing the rules to have proper flex/bison objects generation
dependencies.
The parsers code is not rebuilt until the flex/bison source files
are touched. Also when flex/bison source is changed, only dependent
objects are rebuilt.

Hm, can I cherry-pick this over into perf/urgent? I see no good
reason why we should leave the v3.4 version half-broken.
Thanks,

Feel free! Overcautious me, wanting to push just only strict bug fixes
there, this one I found just a minor annoyance, so left for perf/core.
