nit: "and Mac uses Cocoa"?

yep added "but Mac only links browser parts for the Cocoa implementation."

optional nit: merge this with your nested chromeos==1 block inside the
enable_app_list==1 block above or vice-versa.

Hum - I guess this was from a time when there was a distinct `enable_arc`, but
that's gone. app_list_chromeos_arc_sources should just be folded into
app_list_chromeos_sources. Merged the 'dependencies' bit. (Done.).
