When building for Android, this error manifests itself:

label_file.c:570:7: error: unused variable ‘subs_file’ [-Werror=unused-variable]
  char subs_file[PATH_MAX + 1];

Fix it by moving the variable into the ifdef'd usage block.

FYI this just happened when building with ANDROID_HOST=y on my
development branch, so I am
assuming some Makefile change introduced a hard error on it... inside
the android tree, it was still
building, without even printing a warning as well.
