I have some specific comments below, but as a general question,
how about crosssdk and cross-canadian recipes for the toolchain?
Thanks,

Have you tested to make sure that the go install won't update and
install packages into the staging libdir during this compilation step?
There is that risk, as the go tool will update dependent packages
even in GOROOT if it's writeable. In meta-golang I added some patches
to the go build tool to prevent this.

Perhaps you could use --exclude-vcs and --exclude=pattern on the tar
command to prevent the files from being populated in the first place?

Use --no-same-owner on the tar command to eliminate the chown.

This is a bbclass, so these two functions should not be here, and the
ones above should be named 'go_do_XXX' instead of 'do_go_XXX'. Then
add an EXPORT_FUNCTIONS line to export them.

For the following go-1.4 recipes:
I wouldn't recommend fixing go-native at version 1.4, which is now
postiviely ancient.
Instead, add go1.4.3's SRC_URI into the go-native recipe, loading it
in the right place so
that make.bash finds it. This way, you can have all the go toolchain
recipes build at the
same version. The go team only supports go1.4 for bootstrapping the
compiler build now
anyway, IIRC.

This patch was something that I brought into my go recipes a while back,
but probably isn't upstreamable and isn't generally needed any more.
