#   TARGET_PRODUCT        target device name, e.g., `aosp_blueline`

#   TARGET_BUILD_VARIANT  variant, e.g., `userdebug`

#   OUT_DIR               where the build is happening (./out if not specified)

#   XREF_CORPUS           source code repository URI, e.g.,

#                        `android.googlesource.com/platform/superproject`
