Revert overeager warning for misuse of `--print native-static-libs`

In a PR to emit warnings on misuse of `--print native-static-libs`,
we did not consider the matter of composing parts of build systems.
If you are not directly invoking rustc, it can be difficult to know
when you will in fact compile a staticlib, so making sure everyone
uses `--print native-static-lib` correctly can be just a nuisance.

This reverts the following commits:
- f66787a08d57dc1296619b314d2be596085bfeef
- 72a9219e82c157041bfc8dfd378c9cb2b09c0650
- 98bb597c05c32365abbd6898f278b097352774ed
- c59b70841c36277464b51161e3fcf12dfcb667e0

Next cycle we can reland a slightly more narrowly focused variant or one
that focuses on `--emit` instead of `--print native-static-libs`.
But in its current state, I am not sure the warning is very useful.
