I've not used it directly but it is for cross compiling only.  For
example, if I want to cross compile a cygwin binary under Linux and
have all its internal paths relative to /usr when installed on cygwin
I'd need to "configure --prefix=/usr
--with-sysroot=/usr/i686-pc-cygwin/sys-root/cygwin/lib" so that it can
find cygwin libraries and not my Linux libraries from /usr/lib.

But since I've not used it directly and I'm not positive were you stop
in that path.  I'm not sure if "*/lib" needs to be there or if its
stops all the way at "*/sys-root" part.
