OpenBSD/arm only currently supports softfloat, hence make the default GOARM=5.

This is a reproposal of CL 2957. This reproposal restricts the
scope of this change to just arm systems.
With respect to rsc's comments on 2957, on all my arm hosts they perform
the build significantly faster with this change in place.

We can use processor architecture or hardware platform as part of
hostname and it leads to misconfiguration of GOHOSARCH.

Rather than detecting vfp support via catching SIGILL signals,
parse the contents of /proc/cpuinfo.
As the GOARM values for NaCl and freebsd are hard coded, this parsing
logic only needs to support linux/arm.
This change also fixes the nacl/arm build which is broken because the
first stage of nacltest.bash is executed with GOARM=5, embedding that
into 5g.
The second stage of nacltest.bash correctly detects GOARM=7, but this is
ignored as we pass --no-clean at that point, and thus do not replace
the compiler.
Lastyly, include a fix to error message in nacltest.bash

Bootstrap the Go parts of the Go toolchain using Go 1.4,
as described in https://golang.org/s/go15bootstrap.
The first Go part of the Go toolchain will be cmd/objwriter,
but for now that's just an empty program to test that this
new code works.
Once the build dashboard is okay with this change,
we'll make objwriter a real program depended upon by the build.

Can't use bgwait, both because it can only be used from
one goroutine at a time and because it ends up queued
behind all the other pending commands. Use a separate
signaling mechanism so that we can notice we're dying
sooner.

This CL introduces the bootstrap requirement that in order to
build the current release (or development version) of Go, you
need an older Go release (1.4 or newer) already installed.
This requirement is the whole point of this CL.
To enforce the requirement, convert cmd/dist from C to Go.
With this bootstrapping out of the way, we can move on to
replacing other, larger C programs like the Go compiler,
the assemblers, and the linker.
See golang.org/s/go15bootstrap for details.
