Probably easier to just revert the patch then. We have stopped building
bios-tables-test.c when CONFIG_PARALLEL is not present, so the build
--without-default-devices is already covered.

We would only need those checks if PCI_DEVICES=n or one of the
individual CONFIGs, which we have discussed previously that is not worth
the effort to keep track of.
