I just ran into this strange Travis build issue:

 https://travis-ci.com/huth/qemu/jobs/273007378#L3509

... I think it might be related to this patch?

CONFIG_Q35 only does "imply AMD_IOMMU", so when compiling with
"--without-default-devices", x86-iommu.c is not used... Do
x86_iommu_ir_supported() and x86_iommu_get_type() need to be added to
the x86-iommu-stub.c file?
