    lldb: Fix Architecture parsing by reading the ELF header. (#162811)

    Currently, LLDB in FreeBSD host sets the Process Architecture used by
    lldbserver as Default one. Which cause problem when trying to debug a
    32bit binary on amd64 platform since the lldb itself will found mismatch
    architecture with lldbserver's return.

    Notice that this patch is only a partial fix for the debugging problem.
    We are still unable to debug x86 on x86_64 so that we don't provide
    testcase in this patch.
