You need to name this “proc_maps_linux.cc” or something like that, or exclude it
from the platforms that it’s nonsensical on. Since you want this for both linux
and android, you’ll probably need an exclude (like “sources!”).

The same goes for the unit test.

The code itself might build just fine on other platforms, but it’s pointless and
bloaty to build it elsewhere.

Done.
