/* Override the broken static getauxval from compiler-rt/CRT.
 *
 * The static version reads from __libc_auxv which is NULL in shared libs
 * loaded via dlopen, causing SIGSEGV in init_have_lse_atomics at load time.
 * This version calls the real bionic getauxval via dlsym.
 *
 * Copied verbatim from crates/wzp-android/cpp/getauxval_fix.c — the legacy
 * wzp-android crate has been using this shim successfully for months.
