    lto-wrapper.cc: Add offload target name to 'offload_args' suffix
    
    lto-wrapper.cc's compile_offload_image calls mkoffload with
    an @./a.offload_args argument ('a.' in case of, e.g., 'a.out'). However,
    when generating code for both nvptx and gcn, they use the same name
    with -save-temps. Hence, this commit adds a <target> + '.' before
    'offload_args' in line with other offload-target-specific files.
    
    gcc/ChangeLog:
    
            * lto-wrapper.cc (compile_offload_image): Prefix 'offload_args'
            suffix by the target name.
