This seems to come from constructions of the form

for i in $FOO : do .... ; done

If $FOO is empty, then the resulting "for i in ;" is a syntax error with
some versions of bash and sh. Current Linux versions of bash do not have
that behaviour. As we saw in an earlier post, quotes around $FOO is not
the answer.

One workaround could be to upgrade bash.

Another workaround could be to safeguard the for-loop with

test "$FOO" != "" && for i in $FOO : do .... ; done

in all of the Makefiles where this can be an issue.
