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

In commit e3fe6f5d I manually renamed SYS_SYSCTL to SYS___SYSCTL so that
syscall_bsd.go would continue to build, despite a rename of __sysctl to
sysctl somewhere between these two XNU versions:

    http://www.opensource.apple.com/source/xnu/xnu-2422.90.20/bsd/kern/syscalls.master
    http://www.opensource.apple.com/source/xnu/xnu-2782.1.97/bsd/kern/syscalls.master

In this commit I add a workaround that doesn't require manual edits to
autogenerated output, so regenerating the output should now cause no
diffs.

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 copies http://golang.org/cl/8723 from the syscall package.

Quoting the original CL:

    This is clumsy, but currently cover tool fails as:

    $ go test -run=none -cover syscall
    syscall_linux_amd64.go:15: can only use //go:noescape with external func imp
    FAIL        syscall [build failed]

    This happens because cover tool mishandles //go: comments.
    r and gri said that fixing cover is infeasible due to go/ast limitations.

    So at least fix the offending code so that coverage works.
    This come up in context of coverage-guided fuzzing which works best
    with program-wide coverage.

This brings over three CLs from the main syscall package:
http://golang.org/cl/5833
http://golang.org/cl/5835
http://golang.org/cl/5837

Pipe, Pipe2, and Dup2 are moved from syscall_linux.go to the GOARCH
specific variants.  On 386 and amd64, Linux kernel version 2.6.23 (the
documented minimum Linux kernel version the Go distribution supports)
does not support the pipe2 system call, so Pipe continues to call
pipe.  On ARM, Pipe now calls pipe2.

Several system calls are reimplemented in terms of the *at syscalls,
passing AT_FDCWD to indicate that pathnames are to be interpreted
relative to the current directory.  The *at syscalls were added in
Linux kernel version 2.6.16.

This is in preparation for arm64 support, as the arm64 Linux kernel
does not provide the traditional syscall variants.
