George Sapkin 5657eb0e2e golang: split src into separate packages 
Split misc sources and test data into separate packages. Reduces target
src package size by a third.

Move architecture-dependent generated source from src to the main
package.

Mark doc, misc, src and tests packages with PKGARCH:=all as they don't
have any architecture-specific files.

Fix stripping and strip compiler only.

define Package/golang-bootstrap/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.
