[PATCH] Fix kexec-tools on x86_64

[Bernhard Walle]

This patch fixes kexec-tools on x86_64. The build had two problems:

 1. The distribution missed the files

        purgatory/arch/x86_64/entry64-32.S,
        purgatory/arch/x86_64/entry64.S,
        purgatory/arch/x86_64/setup-x86_64.S,
        purgatory/arch/x86_64/stack.S,
        purgatory/arch/x86_64/purgatory-x86_64.c

    The problem was that variable expansion in a Makefile is a bit different
    from the expectation, i.e. the final value is used even if the variable is
    used in the middle.

 2. The build didn't include the files mentioned above. This was because of
    using '=' instead of '+=' in the 2nd part of the Makefile.
