    # linux/nvme.h has been renamed to linux/nvme_ioctl.h since 4.4,

    # and the efivar source handles that situation. However, some

    # Sourcery CodeBench toolchains use 4.4 kernel headers but they

    # don't have that header file renamed, and that is causing build

    # failures. So, prevent this package to be built using those

    # toolchains.
