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"

these are the ones I tested; kettenis@ was on board with the concept

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.

Strip superfluous parens from return statements while here.

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

_dl_exit() is __dead, so it should return void.
Move _dl_mmap() and _dl_mquery() inlines from archdep.h to syscall.h and
remove pointless casts and unnecessary parens.
