Subject: [PATCH] Workaround app compat issue introduced by global ThinLTO
 optimization

Several obfuscation libraries do not work with ThinLTO optimized bionic
linker. Given we switched on the optimization late in the 24Q3 (V)
release cycle, apply the local opt-out to avoid breaking the apps.

This workaround will be removed in the following Android release.

Test: manual
