go: split out go-runtime into separate recipe
Reorganize the Go toolchain build to split out
the Go standard runtime libraries into a separate
recipe. This simplifies the extension to crosssdk
and cross-canadian builds.
* Adds a patch to the go build tool to prevent it
from trying to rebuild anything in GOROOT, which
is now resident in the target sysroot.
* 'go' bb and inc files are now for building the
compiler for the target only.
* 'go-cross' bb and inc files are now just for
the cross-compiler.
* Adds virtual/<prefix> PROVIDES for the compiler
and runtime
* Removes testdata directories from the sysroot
during staging, as they are unnecessary and
can cause strip errors (some of the test files
are ELF files).
* Re-enables pacakage QA checks, adding selective
INSANE_SKIP settings where needed.
