Commit Message

Zhangfei Gao March 20, 2026, 3:03 p.m. UTC 
Allow configurations to define 'bb-target'.

When set, bitbake-setup creates a setupdir/build-target helper script
that sources build/init-build-env and runs bitbake with the configured
default target (or with arguments provided by the user).

This reduces wrapper-script logic and makes setup usage closer to
one-command project build workflows.
