Since CL 10087 build tags for GOOS and GOARCH are emitted by
mksysctl_openbsd.go but the generated file is always written to
zsysctl_openbsd.go.
Adjust mkall.sh to write to GOOS/GOARCH specific files and create a
zsysctl_openbsd_${GOARCH}.go file for each GOARCH supported on openbsd.

Follow golang.org/cl/55130 and add the utimensat syscall on *BSD. Use it
in UtimesNano and UtimesNanoAt (which is added on *BSD, akin to the
already existing implementation on Linux and Solaris).
Also add AT_FDCWD and AT_SYMLINK_NOFOLLOW where they are missing. These
might be used with UtimesNanoAt.
In order to be able to generate the syscalls, also add two missing
$GOOS_$GOARCH patterns to mkall.sh. As a side effect, some additional
syscalls are added for openbsd/arm.

Right now the process for adding in new constants, errors, or syscalls
for Linux is a pain and unreliable. The scripts are designed to be run
on the target architecture and use the header files installed on the
user's system. This makes it hard to generate files for all the
architectures or to have consistency between users. See golang/go#15282.
This CL fixes this issue by making all of the files for the 11 supported
architectures directly from source checkouts of Linux, glibc, and bluez.
This is done using Docker, the gcc cross-compilers, and qemu emulation.
Previously discussed here:
https://go-review.googlesource.com/c/37589/
A README.md file is also added to explain how all the parts of the build
system work.
In order to get the build working for all the architectures, I made
some changes to the other scripts called from mkall_linux.go:
- Files only used for generating linux code, moved to linux/
- linux/mksysnum.pl supports a specified CC compiler.
- The generated C code in mkerrors.sh changed to avoid a warning
- mkerrors.sh headers changed to fix powerpc64 bug in sys/ioctl.h
- linux/types.go no longer needs to export Ptrace structs in lowercase
Build instructions:
- Host system needs to be x86-64 Linux
- Install Docker (https://docs.docker.com/engine/installation/)
- ./mkall.sh (That's it!!!)

This commit adds linux/s390x support to the unix package. It is
based on the changes made to the syscall package in
https://golang.org/cl/20961/. It also adds mkpost.go which is
used to cleanup the API generated by cgo -godefs.
The biggest departure that is made with the syscall package is
the use of the -fsigned-char flag to force signed chars. We
couldn't do this in the syscall package because of the need to
maintain compatibility with the gccgo implementation of the syscall
package (gccgo has supported s390x for a longer time than the Go
toolchain). The unix package does not have this constraint.
Using the -fsigned-char flag makes the API look more like the one
generated on amd64 and arm64 and also more consistent with itself
(the syscall package represents chars using both int8 and uint8
types, the sys package will only ever use int8). Unfortunately it
also means that applications transitioning from the syscall package
to the unix package will see a different API on s390x which might
be confusing. I think the tradeoff is worth it though.

This makes the script resistant to changes in the SDK location, which
apparently happens from time to time.
While I was at it, made another cosmetic touch-up: use a .gitignore file
to stop `git status` from showing the _obj/ directory generated by
mkall.sh.

I did this on OS X 10.10.5 (14F27) using the OS X 10.10 SDK included in
Xcode 6.4 (6E35b) for syscall numbers. I believe this SDK is intended
for 64-bit Macs, but the syscall numbers aren't likely to vary. See also

I did this on OS X 10.10.5 (14F27) using the 10.10 SDK included in Xcode
6.4 (6E35b). This required removing a C include from mkerrors.sh, since
it doesn't exist on either of my two systems.
I spot checked the syscall number changes against this definitive list,
which is for approximately my kernel version:
http://www.opensource.apple.com/source/xnu/xnu-2782.20.48/bsd/kern/syscalls.master
Everything I examined checked out, including the removed syscalls being
marked as "old" or being described in comments as no longer existing.
There is one exception to the output being cleanly autogenerated: I have
manually renamed SYS_SYSCTL back to SYS___SYSCTL, the name used
previously and still used by syscall_bsd.go. Because it would distract
from this CL, I will fix this in an upcoming CL.

This CL copies to each package of go.sys the files from syscall it will need.
Different directories have different files, but these:
mkall.sh
str.go
syscall.go
mksyscall.pl
race.go
race0.go
syscall_test.go
are copied to all three.
No changes yet, these are just copies. They are not ready to use yet:
package names are wrong, for starters. But this clean copy will make
it easier to follow the changes as the packages are enabled.
