Unfortunately this change breaks the build on my Debian testing box:

I'm not sure why dependencies aren't being generated and object files
aren't being compiled.  Instead it is trying to build blib.a early and
link the floppy image.

Changing back to the absolute path gets the build working again.
Looks like there is more to this problem than just the PERL absolute
path.
