Is there a reason you don't want this in an 'ifdef COMPILE_ENVIRONMENT' as well?  I'd think because of the way 'missing' and the FORCE rule are defined, this rule would execute even though $(MIDL_GENERATED_FILES) no longer depend on midl_done.

This (and others) should be: ifdef COMPILE_ENVIRONMENT

The $(COMPILE_ENVIRONMENT) is expanded before the ifdef, so if COMPILE_ENVIRONMENT is set, this is the same as 'ifdef 1', which would be false (unless you set the variable '1' to something). See 'ifdef variable-name' here: https://www.gnu.org/software/make/manual/html_node/Conditional-Syntax.html

This looks good to me! Though I realized it may be possible to just not recurse into the msaa & ia2 directories if we don't have the compile environment. IOW, what if we added "and CONFIG['COMPILE_ENVIRONMENT']" here? https://dxr.mozilla.org/mozilla-central/rev/14c5bf11d37b9e92d27f7089d9392de2ac339bb3/accessible/interfaces/moz.build#7

That may be simpler, but if there's some reason that won't work I think this is fine to land.

Good call, I'll see if that works...
