    Support profiling PIE [BZ #22284]

    Since PIE can be loaded at any address, we need to subtract load address
    from PCs.

        [BZ #22284]
        * gmon/gmon.c [PIC]: Include <link.h>.
        [PIC] (callback): New function.
        (write_hist): Add an argument for load address.  Subtract load
        address from PCs.
        (write_call_graph): Likewise.
        (write_gmon): Call __dl_iterate_phdr to get load address, pass
        it to write_hist and write_call_graph.
