I am trying to use the Rustup package developed by @Grommish, in a 18.06.5 buildroot on Ubuntu 20.04, but I don't think my question is package-specific. This package has a Host/Install target that I want to invoke by itself, but I don't know how. I know I can do eg.
make package/rustup/host/compile
...to invoke the Host/Compile target. But when I try:
make package/rustup/host/install
...I get:
make[1]: *** No rule to make target 'package/rustup/host/install'. Stop.
How do I invoke the host tool install target?
