$(filter-out $(pattern),$(aList)) doesn't work with '%' in $(pattern)

[gk]

I have used variable filter_out_pattern for convenience only; results are 
the same if you use $(patsubst %,%/\%,$(subDir)) instead.

# Makefile

dirs:=/dir1 /dir1/dir2
subDir:= /dir1
filter_out_pattern:=$(patsubst %,%/\%,$(subDir))

foo:
        @echo dirs=$(dirs)
        @echo filter_out_pattern=$(filter_out_pattern)
        @echo after filtering: dirs=$(filter-out 
$(filter_out_pattern),$(dirs))
        @echo should be: dirs=$(filter-out /dir1/%,$(dirs))


#eof

address@hidden junk]$ make
dirs=/dir1 /dir1/dir2
filter_out_pattern=/dir1/%
after filtering: dirs=/dir1 /dir1/dir2
should be: dirs=/dir1
