Switch i386 and x86_64 to the new CRT layout. The crt0.c body is shared
between all platforms and a small assembler stub in crt0.S is used for
setting up the proper stack and whatever else MD needs.

Extract crti.S and crtn. from the old dot_init.h files. Prepare other
platforms that use the 6-argument form of __(_)start for this.

Rewrite the crtbegin and crtend modules in assembler to make them
compiler independent. Document the interface in README.

Do not pass the main object handle from the assembler startup stub to
the common ___start routine. It's only used for a pointless magic
version check. Thanks to martin@ for testing various architectures.

___start is __dso_hidden, so use CALL_DATUM_LOCAL and drop the PIC
prologue from __start.

fix pic code; otherwise we generate text relocations.

New ___start() C function takes 3 arguments instead of 6 and fetches
argc, argv and environ from ps_strings instead. Adjust the trampoline
accordingly.

Fix brain fart in previous: direct jump is jmp @rN, not bsrf rN.

Since it's in a separate file now, we cannot use direct branch to label.

Asm cosmetic. Add a comment that explains what this trampoline does.

Pass PICFLAGS down to cc-as-as and use __PIC__ to decide if it is small
vs big PIC mode. Retire -DPIC and -DBIGPIC.

Implement crtbegin* for sh3. Tested to work on landisk.

Use unambiguous .p2align 2 since .align 4 copied from i386 is
incorrect, as .align is .p2align on sh3, not .balign

Steal arch/i386/crtend.S
