Details

Actually, Unix/arm platform uses OpenMAX DL for WebAudio. Chromium removes this library due to https://bugs.chromium.org/p/chromium/issues/detail?id=917355 and our copy is from Chromium, so I would like to replace it.

When upgrading NDK to r25+, GNU assembler is removed. OpenMax DL requires -no-integrated-as to build assembler files (due o macro compatibilities), GeckoView cannot move to new NDK version.
