feature request: $(wildcard) file type filter

[Ed Hutchins]

I've recently come up with a nifty way to detect subdirectories:

ALLFILES := $(notdir $(wildcard $(d)/*))
# figure out which files are subdirs by wildcarding on <test>/.
SUBDIRS := $(notdir $(patsubst %/.,%,$(wildcard $(addprefix
$(d)/,$(addsuffix /.,$(ALLFILES))))))

This is useful for scanning whole directory trees automatically, for example.

It would be a lot simpler to support posix find -type style qualifiers
on on $(wildcard):

$(wildcard <patterns>[,<filter>])

where filter is 'f' for plain files, 'd' for directories, 'l' for links, etc.
