I screwed up when I originally imported these files; they're in lib/libc/
in the upstream tree; there is no top-level libc/ (though there is a top-level
common/, so those files stay where they are).

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.

I broke the mips build yesterday because it doesn't use
<private/bionic_asm.h> like the other architectures, including mips64.
I want to move mips closer to mips64 to try to avoid this kind of thing
in future.

This gives us:
* <dirent.h>
struct dirent64
readdir64, readdir64_r, alphasort64, scandir64
* <fcntl.h>
creat64, openat64, open64.
* <sys/stat.h>
struct stat64
fstat64, fstatat64, lstat64, stat64.
* <sys/statvfs.h>
struct statvfs64
statvfs64, fstatvfs64.
* <sys/vfs.h>
struct statfs64
statfs64, fstatfs64.
This also removes some of the incorrect #define hacks we've had in the
past (for stat64, for example, which we promised to clean up way back
in bug 8472078).

bionic/libc/arch-arm64/syscalls/read.S ends with:
b.hi __set_errno
ret
END(read)
If __set_errno returns int, it will set w0 to 0xFFFFFFFF, which means
x0 is 0x00000000FFFFFFFF. When interpreted as a ssize_t that is
INT_MAX, not -1.
Change __set_errno to return long, which will cause x0 to be set instead
of w0.

These were needed when bionic's header files were missing these macros (though
it would have made a lot more sense to just fix the header files!) but cause
warnings now.

We don't need quite so much duplication because we already have a way
to get the signal number from its name, and that already copes with the
fact that the mips/mips64 numbers are different from everyone else's.
Also remove sys_signame from LP64. glibc doesn't have this BSD-ism.

1. Moved arch-specific setup to their own files:
- <arch>/<arch>.mk, arch-specific configs. Variables in those config
end with the arch name.
- removed the extra complexity introduced by function libc-add-cpu-variant-src,
which seems to be not very useful these days.
2. Separated out the crt object files generation rules and set up the
rules for both TARGET_ARCH and TARGET_2ND_ARCH.
3. Build all the libraries for both TARGET_ARCH and TARGET_2ND_ARCH,
with the arch-specific LOCAL_ variables.

Our sigset_t definition hasn't been tied to our NSIG definition since we
switched to uapi headers, so we can now fix it without breaking the LP32 ABI.
The kernel uapi headers define and use _NSIG, so we need to have our scripts
rename the kernel's definitions out of the way, then we can define _NSIG
and NSIG in terms of the kernel's off-by-one value.

No cacheflush for LP64; use the GCC builtin instead. Clean up the
32-bit MIPS implementation now we no longer need to worry about
old versions of GCC.

Remove the linker's reliance on BSD cruft and use the glibc-style
ElfW macro. (Other code too, but the linker contains the majority
of the code that needs to work for Elf32 and Elf64.)
All platforms need dl_iterate_phdr_static, so it doesn't make sense
to have that part of the per-architecture configuration.

Also move some of the stuff that should be in <link.h> out of the
private "linker.h", to make it clearer that these are public API
known to gdb that we can't change.

Most of <machine/_types.h> was either unused, wrong, or identical across
all 32-/64-bit architectures.
I'm not a huge fan of <sys/_types.h> either, but moving the bits we need
up into there is a step forward.

libunwind has #define inline /* empty */ which breaks our fortified headers.
glibc uses __inline but our BSD-derived headers often override that. __inline__
is the third alternative understood by GCC that -- as far as I know -- neither
the C library itself nor third-party code tries to mess with.
