Re: s6: compatibility with make<3.82

It's searching a set of "standard" paths (/lib/ and /usr/lib/) followed by
the LIBDIR macro, which is hard coded to {prefix}/lib in their `build.sh.in
`.
The default prefix is /usr/local, so it's searching in /usr/local/lib.
libskarnet is in /lib/x86_64-linux-gnu/ per Debian's multi-arch standard
(I'm trying to make a Debian package).

I don't see that there's any way to sufficiently alter the LIBDIR macro via
configure options to get the necessary behavior.
I believe I'll have to write a patch for make that is also part of my build
process =(

---
After quite a bit of staring at the debian packaging for make4.0, I've
found they've done exactly that.
i'll have to make this patch part of my build I suppose.
