The getauxval override (dlsym wrapper) fixes SIGSEGV in init_have_lse_atomics at library load time. The current_thread tokio runtime avoids SEGV_ACCERR in pthread_create/__init_tcb. Both fixes are required together. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

// The static version reads from __libc_auxv which is NULL in shared libs

// This version calls the real bionic getauxval via dlsym.
