Second problem is related to cast shell for linux.

If chromecast is "0", then cast shell linux target while compiling will not be
able to find the baseclass of browseraccessibilitymanager since the check
applied here https://codereview.chromium.org/1128183010/patch/220001/230008 and
currently it is a platform check.

So, other option left is chromecast==1. But on making chromecast==1, still cast
shell linux is not able to find the subclass because I think its not able to
satisfy the condition properly hence the files are not getting compiled.

Is this correct to add the files specific to the platform inside the check or do
I need to add in the "private_browser_sources" list and exclude it for the
platforms where it doesn't have to get compiled.
