Instead of this, I would just put at the top:
  assert(is_chromeos)
since if anoybody references something from this file it's a bug.

+  copy("braille_ime_manifest") {
     sources = [
-      "mock_nacl_gdb.cc",
+      "manifest.json",
     ]
-    deps = [
-      "//base",
+    outputs = [
+      "$root_out_dir/resources/chromeos/braille_ime/manifest.json",
     ]
   }
 }
