Joe Richey joerichey@google.com a45f55524b unix: defer Getpagesize() to runtime
In general, page size is not a function of the archetecture. This was
addressed in the Go standard library here:
https://go-review.googlesource.com/25051

This change simply defers to the standard library "syscall" package,
which in turn defers to the runtime. This helps in addressing golang/go#10180 and
also fixes a bug on ppc64.

Currently, we return 65536 as the page size on ppc64, but the kernel
supports 4k and 64k sizes, see here:
http://elixir.free-electrons.com/linux/v4.13/source/arch/powerpc/include/asm/page.h#L24

Now that various page size calculations are not needed, various
components are now dead code and can also be removed. This CL reverts:

Brad Fitzpatrick b0e0dd7297 unix: add openbsd/arm support (in theory)
This copies over some files from the main repo to make the
GOOS=openbsd GOARCH=arm go install and go test -c work.

No clue whether it actually works or not, though. We don't have
builders anymore for this port.

But once this compiles, we'll at least be able to use constants from
the x/sys/unix package from x/net without regressing x/net's support
for openbsd/arm. (If anybody uses openbsd/arm)

Fixes golang/go#10826
