    cdefs: Drop access attribute for _FORTIFY_SOURCE=3D3 (BZ #31383)

    When passed a pointer to a zero-sized struct, the access attribute
    without the third argument misleads -Wstringop-overflow diagnostics to
    think that a function is writing 1 byte into the zero-sized structs.
    The attribute doesn't add that much value in this context, so drop it
    completely for _FORTIFY_SOURCE=3D3.

    Resolves: BZ #31383
