#65371: ccache: implicit declaration of vdupq_n_s32

 Keywords:                |       Port:  ccache
--------------------------+------------------------
 ccache always tests for ARM NEON support regardless of whether building
 its bundled blake3 on Intel or Apple Silicon (see
 [https://github.com/ccache/ccache/blob/v4.6.1/src/third_party/blake3/CMakeLists.txt#L110]),
 and on Intel this leads to a warning about an implicit function
 declaration of `vdupq_n_s32`.

 I’m aware that warnings for functions can be ignored with
 `configure.checks.implicit_function_declaration.whitelist-append`, but is
 there a preferred way of ignoring intrinsics only on non-ARM? Or, should
 ccache change how it checks for/enables NEON support?
