[m-rev.] for review: changes to mmake and bootcheck

[Zoltan Somogyi]

For review by anyone.

For the diff to mmake, the main question is the parsing cost of the spaces.

For bootcheck, my question is not really about the diff, but whether we should
build the slice, profiler, deep_profiler and mfilterjavac directories in stage 3?
At the moment, we do not, so we do not compare them to stage 2. I think
we (I) should fix this. Any objections?

Zoltan.
