This is correct. However, we don't want a comment to show up saying
"you need thread support to enable tcf-agent" if anyway tcf-agent is
not available on the currently selected architecture. So the comment is
not about the architecture dependency, but the comment should not be
displayed if the architectures dependencies are not met.

Just add:

	depends on BR2_PACKAGE_TCFAGENT_ARCH_SUPPORTS

here, so that the comment doesn't show up on unsupported architectures.

Thanks a lot!
