Linux 4.4 moved the NVME ioctl definitions from nvme.h to nvme_ioctl.h in
commit 9d99a8dda154 (nvme: move hardware structures out of the uapi version
of nvme.h), but nvme_ioctl.h was only exported to user space in 4.4.4 in
commit 7712c014b16f64d3 (uapi: update install list after nvme.h rename).

sedutil contains the needed logic to look at either nvme.h or nvme_ioctl.h,
but as the ioctl definitions are not exported in 4.4..4.4.3, it fails to
build.

The MIPS Codesourcery toolchain uses 4.4.1 kernel headers, so disable the
sedutil package if this toolchain is used.
