User theory: tauri-cli hardcodes minSdkVersion=24 into its rustc
invocation regardless of gradle build.gradle.kts, .cargo/config.toml,
or env var overrides — but DOES read from tauri.conf.json's
bundle.android block. That would explain why every cc::Build C++
compile crashed with __init_tcb+4 via pthread_create: API-24 bionic's
.init_array routines for the linked-in .init_array clash with the
pthread_create state tao later expects.
This commit applies the fix AND re-adds the smallest known crashing
variant (E.1 with cpp_link_stdlib('c++_shared')) so the test has one
clear failure mode to compare against:
tauri.conf.json bundle:
"android": { "minSdkVersion": 26 }
build.rs (on android target):
- hello.c (plain C, worked in Step A)
- getauxval_fix.c (plain C, worked in Step D)
- hello2.c (plain C, worked in Step D+1)
- cpp_smoke.cpp (C++ via cc::Build .cpp(true), crashed in E.1)
Also re-emits the libc++_shared.so copy into gen/android jniLibs so
the runtime linker can resolve the NEEDED entry cc-rs added via
cpp_link_stdlib('c++_shared').
If this launches → theory validated, proceed with Oboe integration.
If this crashes → need to keep digging.
