    Perform kernel linker ifunc test only for builds
    
    dvl reported that "make installkernel" failed with "amd64/arm64/i386
    kernel requires linker ifunc support."  This test should apply to builds
    only; the linker is not used at install time.
    
    I think the same (ifunc-supporting) linker used to build the kernel
    should be detected at install time in usual cases (and so not trigger
    this error).  However, there is no reason to disallow the install, if
    for some reason the expected linker isn't the one tested at install
    time.
