spy.test and HP-UX/Tru64 make

[Ralf Wildenhues]

spy.test fails for me on a hppa2.0w-hp-hpux11.11 and on the testdrive
alphaev68-dec-osf5.1b (both with native make).  I believe both failures
not to be related to double-colon rules.

The failure on HP-UX can be treated with some $sleep before another
touch, the Tru64 failure (over that seemingly broken NFS) by updating
an empty file with echo instead of with touch.

OK to apply?  Do you think these issues need more thorough investigation
instead?

Cheers,
Ralf

        * tests/spy.test: Add some $sleep.
        Update empty file with `echo' instead of `touch'.
