I am not an expert in those tools either. However, I don't think there's
any kind of dependency processing. 
ZA: By at large, circular dependency is not a desired situation and any solution that accepts it as a given may succumb to possible situation where the circular dependency has been an error.  I would say that a warning message should come out of any tool that manages a build processes.I do not know about any automated build process, and thus of any dependency processing built in in z/OS.  I wrote my own process which depends on analyzing the output of attempted linkeditting.  I will extend this process to produce a warning message when an attempted circular dependency is in place.

You could try just concatenating the two files and compiling them as a
single unit. Then all the mutually-calling functions would be together.

ZA: I will try that approach (i.e. concatenating the two files) which is now possible, since in PCRE2 I do not need to to refer directly to the external names (which I have to shorten to 8 characters) anymore.  I am using a set of automated '#pragma map' statements instead and I can parameterize my process to look at pcre2_compile and pcre2_study as one unit.  It will require a few changes and improvements, but those could be of general purpose character (i.e. handle all such cases).  
In a way, this situation is a good thing because it will require me to generalize my build process and dependency processing tool even more.
