I have a possible workaround, for microblaze, for this.
Basically it's to force include a class that does:
python __anonymous() {
if bb.data.inherits_class('goarch', d):
if d.getVar('TARGET_ARCH') in ['microblaze', 'microblazeel',
'microblazeeb']:
raise bb.parse.SkipRecipe("Go does not support microblaze.")
}

This patch breaks Microblaze for me.
Microblazeel is not in the list of course, but go doesn't support this
architecture.
During parsing of various things, instead of the component not being available I
now get many many lines similar to:
WARNING: <recipe>: Exception during build_dependencies for GOARCH
WARNING: <recipe>: Error during finalize of <multiconfig>
ERROR: ExpansionError during parsing <recipe>
bb.data_smart.ExceptionError: Failure expanding TARGET_GOARCH, expression was
${go_map_arch(d.getVar('TARGET_ARCH'), d)} which triggered exception KeyError:
'Cannot map architecture microblazeel'
The variable dependency chain for the failure is: TARGET_GOARCH -> GOARCH
(at which point parsing stops)
I see no obvious way here to add an architecture that OE/Poky does not support,
which now makes this a hard error for any architecture not supported by the core
of OE and/or go. (in the case of microblaze, rust and go are likely to never be
supported. So there has to be a way for me to avoid the parse error in these
cases.)

Add a comment explaining what this function does and where the values
come from.
If the architecture isn't know, instead of returning an empty string
which could fail mysteriously, raise a KeyError so it fails quickly.
