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.

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.

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.

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

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.

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.
