I fixed two little bugs in ldso.c:
        - For LDD support we test the old environment variable
        LD_TRACE_LOADED_OBJECTS.
        - Before we init the GOT table of the dynamic loader
        we have to check, if we have a DT_PLTGOT entry.
        If DT_PLTGOT was zero we patch somthing in the header
        of the dynamic loader. This was the cause, why we have to
        enable the DO_MPROTECT_HACKS option for all targets, to avoid
        segment faults.

In readelflib1.c I added a warning, if we try to load a shared library, which
wasn't compiled with -fPIC or -fpic. So if we disable the DO_MPROTECT_HACKS
option we are sure, that we don't waste memory by shared libraries which
aren't able to share their text segment. I think this is a helpful option on
little embedded systems.
