# for all architectures supported by Mainline modules. The make (kati) stage is

# skipped, so the build targets in the arguments can only be Soong modules or

# intermediate output files - make targets and normal installed paths are not

# supported.

# This script is typically used with "sdk" or "module_export" modules, which

# Soong will install in $OUT_DIR/soong/mainline-sdks (cf
