Or, as the comment says, it might be enough just to not get the
package-native-inputs from the package ever, but do hard-code
bc, gcc and kmod. Maybe add a comment why :)
The reason I hadn't done that back then is because it's slightly less
maintenance to not have Linux's native-inputs copy&pasted like this
(one day, Linux could switch the GCC version they use).
But really, we should be good for years anyway.
I'm not sure whether Linux checks whether it's being compiled with the
right compiler, though. If not, that could cause some nasty silent
miscompilations in the future.
