The problem seems to be in remoting/remoting_locales.gni / remoting/tools/build/remoting_localize.py .
"en_US"  is in lists of locales, but remoting_localize.py seems to normalize it to "en" and never generates */en_US.lproj/InfoPlist.strings .
This way, all outputs of "remoting_localize" rule are marked as dirty.
