This nasty dejagnu patch addresses the currently known `make check'
differences in light of different configuration strategies (note that
my workaround code will only kick in when conditions would have been
broken anyways thus I think this is fairly safe to apply even if it is
otherwise broken with remote checking, etc - which it may well be).

With this patch, in-source and out-source configure now seen to have
the same `make check' results on 3.0.X branch.

I know of NO way to do this job properly within TCL exclusively since
'file copy' is broken (at least on some tested platforms and some TCL
versions - I have no idea what the TCL language specification says to
do in this case but seen behavior is quite useless) when working with
a source file that is a relative soft link and the target is in a
directory other than the source file.

If anyone knows a cleaner way to do it, please advise me before I
install this patch on mainline and the 3.0.X branch on Friday.  Yes, I
will add TCL code comment and ChangeLog when I post the final version.
