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 jca@

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.

Like most archs, riscv doesn't need resolution of JUMP_SLOT relocations
in static PIE binaries: delete RELOC_JMPREL and HAVE_JMPREL there.
