The likely cause of the inability to parse the address is the PCI driver
not being linked into the binary for a static build. This could indeed be
caused by incorrect output from pkg-config, and the default pkg-config on
centos 7 is known to have such an issue. Updating pkg-config, or use
pkgconf instead, is recommended to fix this, as suggested above.
