I tried to fix this in a way that would still allow compile tests, but it got too ugly, so this just reverts the patch that allowed it in the first place.
Most architectures do allow enabling PCI, so the value of the COMPILE_TEST alternative was not very high to start with.
I think COMPILE_TEST has value in that it exposed issues in the PCI headers, and in general COMPILE_TEST exposes code that can be simplified/refactored. That said I don't have the time to suggest an alternative at the moment so it's fine with me if you want to revert. If you don't mind sharing your config it'd help me work on this when I get a chance. Thanks!
