# Features resolving.
#
# Inputs:
#   - `FEATURES`: a list of features to be enabled split by spaces or commas.
#     The features can be selected from the crate `axfeat` or the user library
#     (crate `axstd` or `axlibc`).
#   - `APP_FEATURES`: a list of features to be enabled for the Rust app.
#
# Outputs:
#   - `AX_FEAT`: features to be enabled for ArceOS modules (crate `axfeat`).
#   - `LIB_FEAT`: features to be enabled for the user library (crate `axstd`, `axlibc`).
#   - `APP_FEAT`: features to be enabled for the Rust app.
