tbh, you can't easily check for that because the kernel version is rather
meaningless.
for the #defines you can override them (see the patches), for ioctls it's a
bit more complicated. and we backport a lot of features to RHEL kernels, so
a simple version check is actually quite unreliable to begin with.

otherwise, Reviewed-by: Peter Hutterer <peter.hutterer at who-t.net>, thanks!

having (only quickly) looked at this code, I don't think we even need to know about
the type of tarball. "tar xf" is enough for at least GNU tar, no need to
append the compression format. would be interesting to know about the other
platforms here. but if it's not required, we can loop through *.tar.* and
just go from there.
