| |
When making modules_install for an out-of-tree module, the current directory is $(KBUILD_OUTPUT), and the Makefile recipe which verifies the existence of files in include/config is unable to find them using a relative path. This leads to a spurious and puzzling "Kernel configuration is invalid" warning when no configuration is actually needed.
Since the file check is done in a recipe with `test -e' rather than as a target or include, the usual search paths provided by VPATH and -I are not consulted, so an explicit path is needed in this case.
