I don't know why the build system cannot install the appropriate kernel
devel package as a dependency for the kernel. It seems, it is not happy
when kernel--devel is not listed explicitly, starts complaining about
seemingly unrelated packages like this:
plymouth = 0.9.2-4:2016.1 is needed by plymouth-system-theme-0.9.2-4.x86_64
error while checking dependencies
and does not mention the kernel at all.
