 All inputs are optional; if no inputs are provided:
 
 - the Rust compiler fork with Xtensa support will **NOT** be set as the default (but is usable via the `+esp` toolchain specifier)
+- all available build targets will be installed
 - the latest available version of the compiler will be installed
 - [ldproxy](https://github.com/ivmarkov/embuild) **WILL** be installed; this is required for `std`, however installing it significantly increases the total run time of this action
