Upstream's nss-config uses pkg-config for 3 things:
- getting exec_prefix. It's always /usr, independently of the pkg-config
  you use
- getting includedir. It's always /usr/include/nss, independently of the
  pkg-config you use
- getting libdir. This varies dependending on the pkg-config you use,
  but so does the content of the current nss-config, and as was said
  up-thread, nothing uses that.

So really, using upstream's nss-config wouldn't break things more than
they currently are, while it would fix the immediate multi-arch problem.
All the while not breaking any reverse-dependency.
