When a module FOO defines that it should not be cloned recursive by setting FOO_RECURSIVE=NO, the shell variable "recurse" stays set to "--recurse" running git clone.
That setting only works for the first module, i.e. EPICS Base, as the "recurse" variable is global and never gets reset to an empty string between modules.
