beagrep is made even faster

beagrep -e readlink in my android source tree now takes only 0.230 second on Dell Optiplex 960 (cache hot).

The trick I used is to simply enable Mono's AOT option (see git log).

But sadly, I can't improve it on my macbookair with debian installation to the same speed as on my Optiplex 960. This is very strange since the macbookair is a more powerful machine with better CPU and SSD (which does not matter when cache is hot though).

The time on macbookair is consistently ~0.8 second slower than Optiplex 960, AOT or not AOT.
