* mk: provide a mechanism to default to `rc`Dan Cross2021-10-051-0/+2
| | | | | | | | | | | For cross-compiling plan9 from Unix, provide a way to force `mk` to use `rc` instead of `sh` without setting `MKSHELL` in individual `mkfile`s. If the environment variable `FORCERCFORMK` is set, `mk` will default to using `rc`, not `sh`. Signed-off-by: Dan Cross <cross@gajendra.net>
