make check when PWD is set.

[Tanaka Akira <akr@xxxxxxxxxxx>]

`make check' fails if PWD has already symlink AND /bin/sh is bash.
Since bash called by make updates PWD to point Test directory, zsh
accept it.

On the environment which /bin/sh does not update PWD such as Solaris 7,
this problem is not raised.  Of course, it can be raised by invoking
ztst.zsh directly.

Apart from the problem, I think `../Src/zsh ztst.zsh' should be
`../Src/zsh -f ztst.zsh'.

(unset PWD; make check) works well as:

Z:akr@thorax% (unset PWD; make check)
cd Test ; make check

for f in *.ztst; do \
  ../Src/zsh ztst.zsh $f; \

cd.ztst: all tests successful.
