Yeah, we can do something in the config file based on a platform
variable, and then setting the actual commands that way.

I'm curious as to why you think "linux16" doesn't work for Linux,
though.  We use it 100% of the time in Fedora and RHEL, and upstream x86
kernel maintainers have expressed a preference for it.  Using "linux"
instead seems to break much more, for example EDD often does not ever
get exposed to the kernel when it's used.
