Whitespace in $srcdir is going to break the build. I think that we
cannot prevent that by escaping as `make` is notoriously bad in that
regard. Aborting sounds better and maybe something like this could
work:
ln -sf "$srcdir" srcdir
srcdir=srcdir
I'm ok with this version if the solution would not be simple. :)
