cygwin testsuite: Avoid -no-install

[Billinghurst, David (CRTS)]

When running the libjava testsuite on cygwin, there are errors
due to warnings about -no-install.  This is probably required on 
other win32 platforms, too, but I can't test that.

	* testsuite/lib/libjava.exp (libjava_arguments): Don't link
	with -no-install on *-*-cygwin*.
