regression: fakechroot breaks makefiles with $(wildcard ./*/.)

[rgenoud]

Since commit c996fc4121f29 ("Imported Upstream version 2.17"), fakechroot make mismatches files as directories: Makefile:

subdirs := $(wildcard ./*/.)

all:
	@echo "$(subdirs)"

The make command will return only directories, whereas fakechroot make will return also files.
