OK this is bogus, but the failure is because of where we get uint32_t
from (hint using arm32 compiler on a arm64 system) so I got:

  lib/pci.c:71:9: error: format '%x' expects argument of type 'unsigned int', but argument 3 has type 'uint32_t {aka long unsigned int}' [-Werro\
r=format=]

Which makes me think we should be more careful about including system
headers in kvm-unit-tests (done in 75e777a0).
