Few fixes to be able to use GCC extensions which are not
available on Clang.

Since RFC:
- Split Clang __builtin_available() patch
- Do not un-inline qemu_thread_jit_execute/write
- Do not use #pragma diagnostic
- Demote ui/cocoa key arrays to static const
- Lookup scripts/entitlement.sh script once again
- Pass filtered QEMU_OBJCFLAGS configure -> meson
- Disable out-of-line atomic operations on Aarch64

Philippe Mathieu-Daudé (8):
  osdep: Avoid using Clang-specific __builtin_available()
  osdep: Ignore 'unguarded-availability-new' warnings on macOS Catalina
  meson: Resolve the entitlement.sh script once for good
  configure: Disable out-of-line atomic operations on Aarch64
  meson: Log QEMU_CXXFLAGS content in summary
  configure: Pass filtered QEMU_OBJCFLAGS to meson
  audio: Rename coreaudio extension to use Objective-C compiler
  ui/cocoa: Constify qkeycode translation arrays
