This is for fixing the following error of 'bitbake meta-go-toolchain'
when multilib is enabled:
Error: Transaction test error:
   file /usr/bin/go conflicts between attempted installs of go-1.25.4-r0.x86_64_v3 and lib32-go-1.25.4-r0.core2_32
   file /usr/bin/gofmt conflicts between attempted installs of go-1.25.4-r0.x86_64_v3 and lib32-go-1.25.4-r0.core2_32

Why would you do this though?  We don’t support installing bash and lib32-bash either.

If the goal is “I want to build 32-bit go apps in my 64-bit userspace” then luckily go is always a cross-compiler and you can just set GOARCH when building with the standard go.

Hi, Ross

The issue reproduced when multilib is enabled globally in local.conf by 
following config:

```

require conf/multilib.conf
MULTILIBS ?= "multilib:lib32"
DEFAULTTUNE:virtclass-multilib-lib32 ?= "core2-32"

```

bitbake meta-go-toolchain will failed with above failure.

[snip of meta-go-toolchain.bb]

TOOLCHAIN_TARGET_TASK:append = " \ ${@multilib_pkg_extend(d, 
'packagegroup-go-sdk-target')} \ "

[snip of meta-go-toolchain.bb]


go is in packagegroup-go-sdk-target,  it is extended by 
multilib_pkg_extend.  so both go and lib32-go will be installed.

go is added in to packagegroup-go-sdk-target for providing entire 
toolchain include compiler.


Regards

Changqing

Maybe the packagegroup shouldn’t be doing that expansion then?

We don't want go to be extended, but packagegroup-go-sdk-target not only include go, it also includes go-runtime/go-runtime-dev, we need to extend go-runtime/go-runtime-dev.

so fix go packaging for multilib as this patch to avoid the conflicts issue.
