RFR: CODETOOLS-7902417: jtreg build with build-all.sh should work on cygwin

[Jonathan Gibbons]

Christoph,

I'll take a look at this today; I can check Linux/Mac, and sponsor it if 
all seems OK.

At some point, someone is going to want support for WSL (Windows 
Subsystem for Linux) as well, but I realize that is only for Windows 10.
