FWIW, -L is POSIX:

It may be that MSys dropped the option due to Windows not having
symlinks, although silently ignoring it would have been better.

7.0 uses $(wildcard ...) instead of "find". That could be used, or
alternatively:

ifneq ($(strip $(MINGW)),)
	FIND = find
else
	FIND = find -L
endif
