I wouldn't say hwloc is tainted, more that you were tainting the GPL'd
code by linking the proprietary code to it, but that's just case of
After a brief search of the GPL FAQs I'd say the closest I can get is:
# I'd like to incorporate GPL-covered software in my proprietary
# system. Can I do this by putting a wrapper module, under a
# GPL-compatible lax permissive license (such as the X11 license)

# No. The X11 license is compatible with the GPL, so you can add a
# module to the GPL-covered program and put it under the X11 license.
# But if you were to incorporate them both in a larger program, that
# whole would include the GPL-covered part, so it would have to be
# licensed as a whole under the GNU GPL.
# The fact that proprietary module A communicates with GPL-covered
# module C only through X11-licensed module B is legally irrelevant;

So yes, if you want to permit proprietary code to link to hwloc then
you need to stick to permissive licenses in hwlocs dependencies.

Of course it might be possible to ask the pciutils maintainer to split
out libpci from pciutils and LGPL it.
Interestingly, Steam for Linux appears to have linked to libpci..
