The makefile is missing the needed ifdef. Trivial patch coming up.

Comment on attachment 542044 [details] [diff] [review] Add missing ifdef Wow, I had forgotten about this little | ifneq (cocoa,$(MOZ_WIDGET_TOOLKIT))| wart. Thanks for reminding me.
Verified that file dom/ipc/Makefile.in is updated in mozilla-central repository. Is this enough to verify the bug as verified-fixed? Thank you!
