# build-android.sh - build the Android SERVER libMobileGL.so (NDK, arm64-v8a) that the anland APK embeds.
# Output: $MGL_WORKTREE/build-android/libMobileGL.so (RelWithDebInfo, unstripped, ~320 MB; keep it for
# llvm-addr2line, it is what cyc.sh pushes).  Stamp = worktree HEAD, so the container client
# (xbuild.sh, same stamp) and the server agree on the build ("compatible wire with different build"
# WARN otherwise).  Env: MGL_WORKTREE, ANDROID_NDK, BUILD_DIR (default build-android), JOBS (12).
# Log level is compiled to INFO.  android-30 = the APK's minSdk: thread_local is then the platform's
# own TLS rather than the emulated one (which cost 7-12% of an apply thread on the API 26 build).
