FYI: Make for faster windows build

[Lubos Lunak]

 Looks what I found under the tree! Faster make for Cygwin. Granted, I had put 
it there first, but still nice.

 Those of you who build on Windows, you might want to pull again from 
git://gerrit.libreoffice.org/dev-tools.git and update your make. I've 
implemented built-in support for some simple commands used by gbuild such as 
mkdir or cp, and since fork() is pretty slow on Cygwin, this makes some 
operations such as delivering noticeably faster. Tinderbox #6 has been using 
it for two weeks without a problem.
