prebuilts.
This runs Soong in skip-make mode, using normal in-make mode only to query
platform versions.
The same ${OUT_DIR} cannot be used for both skip-make and in-make builds,
because Soong generates a smaller build.ninja file in in-make builds where
many build targets are expected to be provided by the mk files. Thus this
script avoids using ${OUT_DIR} if it's an in-make build, defaulting instead
to out-aml/.
The script is based on build-ndk-prebuilts.sh, but uses a separate Soong
variable Aml_abis to enable the appropriate target architectures for
Mainline modules. Aml_abis is very similar to Ndk_abis, except "armeabi-v7a"
is used instead of "armeabi", which is necessary to match prebuilt
dependencies, e.g. for LLVM.
Test: build/soong/scripts/build-aml-prebuilts.sh libart libdexfile_external
(verify that libraries for arm, arm64, x86, x86_64 are built)
Test: build/soong/scripts/build-aml-prebuilts.sh \
out-aml/soong/.intermediates/external/conscrypt/conscrypt-module-sdk/android_common/conscrypt-module-sdk-current.zip
(verify that the zip file contains libconscrypt_jni.so's for all four arches)
Test: build/soong/scripts/build-aml-prebuilts.sh com.android.art.{release,debug,testing,host}
(verify that the build completes)
Test: Two identical build/soong/scripts/build-aml-prebuilts.sh runs after each other
(verify that the 2nd run completes both Soong and ninja steps quickly without any building)
