crt0 uses a helper function in a MD src/libexec/ld.so .h file (rather than
reproducing the relevant defines and code in a different place) to perform
minor relocations. If things go very wrong, it would call _dl_exit() --
a locally defined crt0 function which is syscall exit(2). We don't need
to call exit(2) for this obscure case which doesn't happen and provides no
debugging information. An 'abort' is going to provide better information.
So let's change the function name to _dso_abort() and make it a single
illegal instruction.

Nothing depends on archdep.h pulling in other #includes anymore,
so delete the #includes and hide the RELOC_* functions that are
only used by lib/csu behind "#ifdef RCRT0"

ok aoyama@

Delete all the no-op RELOC_GOT() macros and their uses.
Annotate RELOC_DYN() on non-hppa as only used in lib/csu.
Delete some inconsistent comments, adjust whitespace, and reorder
mips64's archdep.h so that the ld.so/*/archdep.h files look
(almost) the same.

On fatal errors, kill ourselves with thrkill(0,9,NULL) instead of
simply exiting, via helper functions _dl_die(), _dl_diedie(), and

Remove dependency on __got_{start,end} symbols and look at PT_GNU_RELRO
instead. Result in a few more pages that aren't writable on some platforms
(such as hppa). Based on an initial diff from guenther@.

Thanks to deraadt@ for testing.

Simplify the relocation code for the ld.so bootstrap and static pie: track
just the dynamic tags are needed instead of reusing the generic elf_object_t
structure.

A first cut at ld.so bits for m88k. Lazy binding is currently disabled as it
does not work beyond the first few lazy resolver calls. But that's already
enough to run simple binaries.
