Use <uptodate> to set a property if foo is not newer than foosrc and
add an unless attribute to the foo-Target.

In Ant 1.3 your problem could be solved as

<transform executable="foomaker">
  <srcfile />
  <fileset dir="." includes="foosrc" />
  <mapper type="glob" from="foosrc" to="foo" />
</transform>
