The change in src/liblink/asm5.c silences a warning building
on modern macOS, which doesn't actually produce a working
toolchain anyway, but it still seems worth silencing the warning.
These warnings surface now in the reproducible builds reports
(for example https://gorebuild.storage.googleapis.com/gorebuild.html,
click on "Bootstrap go1.4"). I'd rather not look at them anymore.
For golang/go#58884.

supported on linux
This is a backport of https://golang.org/cl/18359 to the Go 1.4 branch.
This fixes the Go 1.4 build on systems for which the compiler defaults
to using PIE. Such systems are becoming more common.
Original CL description:
Go fails to build on a system which has PIE enabled by default like this:
/usr/bin/ld: -r and -pie may not be used together
collect2: error: ld returned 1 exit status
The only system I know that has this property right now is Ubuntu Xenial
running on s390x, which is hardly the most accessible system, but it's planned
to enable this on amd64 soon too. The fix is to pass -no-pie along with -Wl,-r
to the compiler, but unfortunately that flag is very new as well. So this does
a test compile of a trivial file to see if the flag is supported.

This is a cherry-pick of https://go-review.googlesource.com/21190
to release-branch-go1.4. Diff prepared by Ian Lance Taylor.
linux/386 depends on modify_ldt system call, but recent Linux kernels
can disable this system call. Any Go programs built as linux/386
crash with the message 'Trace/breakpoint trap'.
The kernel config CONFIG_MODIFY_LDT_SYSCALL, which control
enable/disable modify_ldt, is disabled on Amazon Linux 2016.03.
This fixes this problem by using set_thread_area instead of modify_ldt
on linux/386.

to the release-branch-go1.4
In the beta version of the macOS Sierra (10.12) release, the
gettimeofday system call changed on x86. Previously it always returned
the time in the AX/DX registers. Now, if AX is returned as 0, it means
that the system call has stored the values into the memory pointed to by
the first argument, just as the libc gettimeofday function does. The
libc function handles both cases, and we need to do so as well.

escaping
The compiler has a phase ordering problem. Escape analysis runs
before wrapper generation. When a generated wrapper calls a method
defined in a different package, if that call is inlined, there will be
no escape information for the variables defined in the inlined call.
Those variables will be placed on the stack, which fails if they
actually do escape.
There are probably various complex ways to fix this. This is a simple
way to avoid it: when a generated wrapper calls a method defined in a
different package, treat all local variables as escaping.
Fixes #9537.

CL 2789 backported a change that required a barrage of followup CLs.
This CL backports all the followup CLs together.
There are manual edits to os_plan9.go and syscall_windows.go to take
the place of edits to defs_windows_{amd64,386}.go and os2_plan9.go
in the original. Those files do not exist in the release branch, but the
definition being added must go somewhere.
Original change descriptions below.

runtime/cgo: initialize our pthread_create wrapper earlier on openbsd
This is a genuine bug exposed by our test for issue 9456: our wrapper
for pthread_create is not initialized until we initialize cgo itself,
but it is possible that a static constructor could call pthread_create,
and in that case, it will be calling a nil function pointer.
Fix that by also initializing the sys_pthread_create function pointer
inside our pthread_create wrapper function, and use a pthread_once to
make sure it is only initialized once.
Fix build for openbsd.

runtime/cgo: remove unused variable
I missed this one in golang.org/cl/2232 and only tested the patch
on openbsd/amd64.

runtime: skip TestCgoExternalThreadSIGPROF on OS X 10.6
The test program requires static constructor, which in turn needs
external linking to work, but external linking never works on 10.6.
This should fix the darwin-{386,amd64} builders.

Shell out to `uname -r` this time, so that the test will compile

Pointers to zero-sized values may end up pointing to the next
object in memory, and possibly off the end of a span. This
can cause memory leaks and/or confuse the garbage collector.
By putting the overflow pointer at the end of the bucket, we
make sure that pointers to any zero-sized keys or values don't
accidentally point to the next object in memory.

no pointers.
malloc checks kindNoPointers and if it is not set and the object
is one pointer in size, it assumes it contains a pointer. So we
must set kindNoPointers correctly; it isn't just a hint.
