    kernel: Implement ELF auxinfo entry type AT_EXECPATH
    
    Refer to issue 2005.
    The new RTLD can optionally use AT_EXECPATH for some of its new
    functionality such as libmap.conf and dynamic token expansion.
    In the absence of this kernel support, RTLD has a fallback
    mechanism that works most of the time, but using it takes a
    performance hit.
    
    This patch was tested for some time by various people prior to
    the 2.10 branch being created.
