    rump kernels: Handle rumpxen host in configure
    
    Support
       ./configure --host=x86_64-rumpxen-netbsd
       ./configure --host=i386-rumpxen-netbsd
    
    Setting --host tells configure we are cross compiling and therefore
    has various automatic effects.
    
    But in this patch we make some deliberate changes as well:
     * We disable a large number of configure tests for libraries
       etc. which don't exist.
     * We set CONFIG_RUMP in Tools.mk.
     * Hence, we automatically set XEN_OS.
    
    (I have only tested the 32-bit build but I think the 64-bit build
    should work just as well.)

    v3: Add comment to `fi'
    v2: Mention x86_64.
        Drop an erroneous whitespace change.
