    kernel-arch.bbclass: conditional error message
    
    The single purpose of "map_kernel_arch" is to set
    
       export ARCH = "some-arch"
    
    The case when "some-arch" is not a valid Linux architecture results in an error.
    This makes sense if the TARGET_OS is Linux, but that is not always the case.
    kernel-arch is also inherited by toolchain-script, which may be used to build
    toolchains for architectures not supported by Linux.
    
    Rather than modifying toolchain-script to provide its own version of "map_arch"
    this patch bypasses the error if the TARGET_OS is not linux.
