nogo: golink uses the wrong cc linker on MacOS with DEVELOPER_DIR set

What version of rules_go are you using?

v0.44.2

What version of gazelle are you using?

v0.35.0

What version of Bazel are you using?

Bazel 7

Does this issue reproduce with the latest releases of all the above?

These are the latest

What operating system and processor architecture are you using?

MacOS Intel, specifically Github Action runner macos-13

Any other potentially useful information about your toolchain?

Default apple_support cc toolchain is disabled with --repo_env=BAZEL_NO_APPLE_CPP_TOOLCHAIN=1
Default unix toolchain is setup normally
Set --action_env and --host_action_env with DEVELOPER_DIR="/Library/Developer/CommandLineTools"
Set --host_linkopt="-Wl,-v" to make ld prints out it's version.

What did you do?

bazel build //... in https://github.com/buildbuddy-io/buildbuddy

What did you expect to see?

The same ld linker under /Library/Developer/CommandLineTools is used for all actions.

For example, here is the correct linker being used for linking protoc. Note the [for tool] indicating that this is an action using exec configuration.

What did you see instead?

GoLink under nogo (in our repo the target is named vet_actual) would use a different linker than the rest https://github.com/bazelbuild/rules_go/blob/3c51b967ffaeb321634239d34d837bbfc0a17caa/go/private/rules/nogo.bzl#L134-L135

From the same build as the protoc log above would print this:

So for some reason, the GoLink action is setting up cgo portion of the action wrongly 🤔

bazel-contrib / rules_go
