    zfs: emit .note.GNU-stack section for all ELF targets
    
    On FreeBSD, linking the zfs kernel module with binutils ld 2.44 shows
    the following warning:
    
        ld: warning: aesni-gcm-avx2-vaes.o: missing .note.GNU-stack section implies executable stack
        ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker
    
    Some of the `.S` files under `module/icp/asm-x86_64/modes` check whether
    to emit the `.note.GNU-stack` section using:
    
        #if defined(__linux__) && defined(__ELF__)
    
    We could add `&& defined(__FreeBSD__)` to the test, but since all other
    `.S` files in the OpenZFS tree use:
    
        #ifdef __ELF__
    
    it would seem more logical to use that instead. Any recent ELF platform
    should support these note sections by now.
