It seems that in GNU make, the include directories are not searched using globs. You can test this with:

root/
   Makefile - include foo*.mk
   dir1
      fooa.mk

make -Idir1 gives "foo*.mk: No such file or directory", but if you change the include to fooa.mk explicitly, it works.

if (stmt->should_exist) {
if (files->empty()) {
