Use touchy rather than touch when building on Windows
With Windows 7 in a vitrual box VM on OS X, some very odd things happen
with dates and time stamps when SSHing into cygwin. e.g. here the
"Change" time is in the past:
$ date; touch foo; stat foo
Fri Dec 2 16:58:07 GMTST 2011
File: `foo'
Size: 0 Blocks: 0 IO Block: 65536 regular
empty file

And if we copy such a file, then the copy is older (as determined by the
"Modify" time) than the original:
$ date; touch foo; stat foo; cp foo bar; stat bar
Fri Dec 2 16:59:10 GMTST 2011

This means that make thinks that things are out of date when it
shouldn't, so reinvokes itself repeatedly until the MAKE_RESTARTS
infinite-recursion test triggers.
The touchy program, like most other programs, creates files with both
Modify and Change in the past, which is still a little odd, but is
consistent, so doesn't break make.
