Hmm chrome_child_dll shouldn't depend on browser things (and a dependency wasn't
required here before, unless this is the propagation of the dependency removed
in chrome_renderer.gypi? if so we'll need to add common code for whatever piece
is common).

Yes, it was the propagation of the dependency removed from chrome_renderer.gypi.

The dependency was due to chrome_main_delegate.cc calling
RecordStartupProcessCreationTime() and RecordMainEntryPointTime(). There is no
reason to call these methods from a renderer process (they just set global
variables, which is useless unless we call other startup metric utils functions
later). Therefore, I added some "#if !defined(CHROME_MULTIPLE_DLL_CHILD)" to
eliminate the dependency between the renderer code and startup_metric_utils.
