A test case (vect-early-break-no-epilog_11.c) was modified to require AVX512F support at runtime (avx512f_runtime) instead of only at compile time (avx512f_hw). This ensures that the test is only run on systems that actually have AVX-512 support available during execution, preventing false positives when cross-compiling or testing on systems without the necessary hardware.
