Don't perform CET run-time check for host when cross compiling. Instead, enable CET in cross compiler if possible so that it will run on both CET and non-CET hosts. config/ PR bootstrap/94998 * cet.m4 (GCC_CET_HOST_FLAGS): Enable CET in cross compiler if possible. libiberty/ PR bootstrap/94998 * configure: Regenerated. lto-plugin/ PR bootstrap/94998 * configure: Regenerated.
