Now any core dumps will be useless?

I believe core dumps should be fine.  We include the ELF auxv values in core
dumps as a NT_PROCSTAT_AUXV note that GDB (and I presume LLDB) both look at
to determine the location of the main executable (AT_BASE).  Once the dynamic
section of the main executable is found, DT_DEBUG is used to find the linked
list of shared libraries (including rtld itself) just as with PDEs.
