2.4 mkdep and symlinked kernel source

The recent changes to mkdep can create incorrect dependencies when
(a) the kernel source is a symlink and
(b) you cd to the symlink and
(c) your shell exports PWD.

This one line patch against 2.4.3-pre2 gives consistent results.
Please report any problems to kaos@ocs.com.au.
