Why should it be any of those?  It's just runtest, not
$target-runtest.  The line gets overridden anyway if you run make
check up a directory, I imagine that's why I never see it.

Anyway, gcc uses:

AR_FOR_TARGET := $(shell \
  if [ -f $(objdir)/../binutils/ar ] ; then \
    echo $(objdir)/../binutils/ar ; \
  else \
    if [ "$(host)" = "$(target)" ] ; then \
      echo $(AR); \
    else \
       t='$(program_transform_name)'; echo ar | sed -e $$t ; \
    fi; \

So I would imagine that removing the '' is all it takes.  Or maybe
those are wrong too, I don't think they get used much.
