As I don't really know what the problem ist, I have to guess here. As I
understand it, linking against -lpci without linking -lz at the same
time yields a linker error on FreeBSD.

This does not include "-lpci" anymore. It should succeed on every system
where the include file pci/pci.h can be found. But that has already been
checked on the previous check. The "--print-file-name" calls thus never
seem to get executed.
