Since this is all sort of experimental at the moment, your patch is
okay. I think we should revisit it at a later time so that we (re)use the
information that's already being fetched by solib-svr4.c. (We'll need
to allocate some space for the link map address though.)
With regard to the main executable, it can either be saved separately,
or put on the so_list chain.
BTW, have you answered Daniel's question about how a gdbserver (or
some other debug agent) should fetch the link map address? I.e,
is something like the qSymbol packet going to be needed?
