44-define-linker.patch

[Akim Demaille]

I must say I don't understand very well why this patch is needed, but
it is.  I found it back in the old code, which was doing it for
unconditionally defined sources, but not for conditionally defined
sources (which was a bug).

Now it works for both.

        $linker if there are no @files.
