[PATCH v2 2/8] osdep: Ignore 'unguarded-availability-new' warnings on macOS Catalina

[Philippe Mathieu-Daudé]

When building with GCC on macOS Catalina we get 2254 times:

  include/qemu/osdep.h:780:5: warning: 'pthread_jit_write_protect_np' is only 
available on macOS 11.0 or newer [-Wunguarded-availability-new]
      pthread_jit_write_protect_np(true);
      ^~~~~~~~~~~~~~~~~~~~~~~~~~~~

Fix by using a stricker toolchain version low range, replacing
MAC_OS_X_VERSION_MAX_ALLOWED by MAC_OS_X_VERSION_MIN_REQUIRED.
