I don't know if this one affects Asterisk, but here are the details of one
which breaks OpenRadius.

Definitely. The offending fragment is

SUBDIRS         := auto sysdefs misc str buffer fastring stream strio
                   hash db tests

$(foreach dir,$(SUBDIRS),$(eval include $(dir)/Rules.mk))

If you replace it with the old style

dir             := auto
include         $(dir)/Rules.mk

dir             := sysdefs
include         $(dir)/Rules.mk

etc., it will work with older versions. No idea why Make 3.80 would barf
at that foreach, especially when 3.80 on Linux seemed to work fine...
