This is converging the recipes for go from
meta-virtualization and oe-meta-go

Add recipes for go 1.7

go.bbclass is added to ease out writing
recipes for go packages

+From: Paul Gortmaker <paul.gortma...@windriver.com>
+Date: Tue, 29 Mar 2016 21:14:33 -0400
+Subject: [PATCH] go-cross: backport "cmd/link: support new 386/amd64
+ relocations"
+
+Newer binutils won't support building older go-1.4.3 as per:
+
+https://github.com/golang/go/issues/13114
+
+Upstream commit 914db9f060b1fd3eb1f74d48f3bd46a73d4ae9c7 (see subj)
+was identified as the fix and nominated for 1.4.4 but that release
+never happened.  The paths in 1.4.3 aren't the same as go1.6beta1~662
+where this commit appeared, but the NetBSD folks indicated what a
+1.4.3 backport would look like here: https://gnats.netbsd.org/50777
+
+This is based on that, but without the BSD wrapper infrastructure
+layer that makes things look like patches of patches.

+SUMMARY = "Go programming language compiler"
+DESCRIPTION = " The Go programming language is an open source project to make \
+ programmers more productive. Go is expressive, concise, clean, and\
+ efficient. Its concurrency mechanisms make it easy to write programs\
+ that get the most out of multicore and networked machines, while its\
+ novel type system enables flexible and modular program construction.\
+ Go compiles quickly to machine code yet has the convenience of\
+ garbage collection and the power of run-time reflection. It's a\
+ fast, statically typed, compiled language that feels like a\
+ dynamically typed, interpreted language."

Looking at these recipes and they seem like a good starting point.
I did have some issues though:

* bitbake go - didn't create any target installable packages, although the
  .../image directory seemed to be well populated.
* bitbake go-helloworld - had these errors:
ERROR: go-helloworld-0.1-r0 do_populate_lic: QA Issue: go-helloworld: LIC_FILES_CHKSUM points to an invalid file: /MIT [license-checksum] ERROR: go-helloworld-0.1-r0 do_compile: Function failed: do_compile (log file is located at /build/p0382_2016-01-13/tmp/work/cortexa9hf-neon-amltd-linux-gnueabi/go-helloworld/0.1-r0/temp/log.do_compile.31170) ERROR: Logfile of failure stored in: /build/p0382_2016-01-13/tmp/work/cortexa9hf-neon-amltd-linux-gnueabi/go-helloworld/0.1-r0/temp/log.do_compile.31170
Log data follows:
| DEBUG: Executing shell function do_compile
| stat helloworld.go: no such file or directory
| WARNING: exit code 1 from a shell command.
| ERROR: Function failed: do_compile (log file is located at /build/p0382_2016-01-13/tmp/work/cortexa9hf-neon-amltd-linux-gnueabi/go-helloworld/0.1-r0/temp/log.do_compile.31170) ERROR: Task (/local/poky-cutting-edge/meta/recipes-extended/go-examples/go-helloworld_0.1.bb:do_compile) failed with exit code '1'

I forced the compiler to my target (rsync is _my_ friend) and was
able to run 'helloword.go'.  I've not tested much past this point,
but I am enthusiastic about getting 'go' into OE-core
