go: Add recipes for golang compilers and tools
* 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 * go-examples: Add an example, helloworld written in go This should serve as temlate for writing go recipes * Disable for musl, at least for now * Disable for x32/ppc32 which is not supported Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

+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."
