996524383f Don't zero r1 on entry to the dynamic linker.
There's no need: __linker_init only takes one argument.

Also remove the arm __CTOR_LIST__; we use .init_array and .fini_array instead
of .ctor and .dtor anyway, and I don't think we've ever supported the latter.

851e68a240 Unify our assembler macros.
Our <machine/asm.h> files were modified from upstream, to the extent
that no architecture was actually using the upstream ENTRY or END macros,
assuming that architecture even had such a macro upstream. This patch moves
everyone to the same macros, with just a few tweaks remaining in the
<machine/asm.h> files, which no one should now use directly.

I've removed most of the unused cruft from the <machine/asm.h> files, though
there's still rather a lot in the mips/mips64 ones.

d1973ca513 bionic: rename aarch64 target to arm64
Rename aarch64 build targets to arm64.  The gcc toolchain is still
aarch64.

42b2c6a5ee Clean up the argc/argv/envp/auxv handling.
There's now only one place where we deal with this stuff, it only needs to
be parsed once by the dynamic linker (rather than by each recipient), and it's
now easier for us to get hold of auxv data early on.

20c4a3a8ee Replace .S version of x86 crtfiles with .c version
This patch replaces .S versions of x86 crtfiles with .c which are much
easier to support. Some of the files are matching .c version of Arm
crtfiles. x86 files required some cleanup anyway and this cleanup actually
led to matching Arm files.

I didn't change anything to share the same crt*.c between x86 and Arm. I
prefer to keep them separate for a while in case any change is required
for one of the arch, but it's good thing to do in the following patches.

6973e3da87 Define __stack_chk_fail_local.S
With -fstack-protector, x86 -m32 needs __stack_chk_fail_local
defined in crtbegin_*.o.

Include __stack_chk_fail_local.S in begin.S otherwise linker
(which is built w/o crt*) may not link.

70b1668a76 remove obsolete SuperH support
We don't have a toolchain anymore, we don't have working original
kernel headers, and nobody is maintaining this so there is really
no point in keeping this here. Details of the patch:

- removed code paths from Android.mk files related to the SuperH
  architecture ("sh")

- removed libc/arch-sh, linker/arch-sh, libc/kernel/arch-sh

- simplified libc/SYSCALLS.TXT

- simplified the scripts in libc/tools/ and libc/kernel/tools
