new binary of rockbox utility for me to test.

[alex wallis]

Hi.
I see that Domonoky has posted a patch to fs #10205 that should deal with 
some accessibility problems.
I am happy to test it, if someone could make available a binary including 
this patch.
Is it correct that rockbox utility can't be compiled under cygwin? if it can 
be, then I am happy to compile my own version, its just I am sure I read 
somewhere that rbutil can't be compiled with cygwin.
