I think that this will still result in many GPL-enabled hwlocs by default because libpci is installed on many distros by default, but libpciaccess is not.

How about:

- Check for libpciaccess. If found, use it. STOP.
- If not found:
  - check for libpci.
  - if found, and if --enable-gpl-taint was specified, use it. STOP.
  - if not found, display the usual "no pci support" message at the end. STOP.
  - if found:
    - display the usual "no pci support" message at the end
    - but also display a big, bold, flashing message saying "We can enable PCI support in one of two ways: 1) download/install libpciaccess (http://cgit.freedesktop.org/xorg/lib/libpciaccess/), or 2) pass --enable-gpl-taint to allow hwloc to use libpci, BUT BE AWARE THAT THIS MAKES THIS HWLOC BINARY AND EVERYTHING THAT IT LINKS TO BE GPL!"
