John Ericson 9d25ccf0e8 Change built-in kernel targets to be os = none throughout ... Whether for Rust's own `target_os`, LLVM's triples, or GNU config's, the OS-related have fields have been for code running *on* that OS, not code that is *part* of the OS. The difference is huge, as syscall interfaces are nothing like freestanding interfaces. Kernels are (hypervisors and other more exotic situations aside) freestanding programs that use the interfaces provided by the hardware. It's *those* interfaces, the ones external to the program being built and its software dependencies, that are the content of the target. For the Linux Kernel in particular, `target_env: "gnu"` is removed for the same reason: that `-gnu` refers to glibc or GNU/linux, neither of which applies to the kernel itself. Relates to #74247 Thanks @ojeda for catching some things.		2021-03-01 12:46:25 -05:00
