I verified that without the guard accounting change in commit630f4cc3aa(Fix stack guard size accounting) and RTLD_NOW for libgcc_s introduced by commitf993b87540(nptl: Open libgcc.so with RTLD_NOW during pthread_cancel), the tst-minstack-cancel test fails on an AVX-512F machine. tst-minstack-exit still passes, and either of the mentioned commit by itself frees sufficient stack space to make tst-minstack-cancel pass, too.
