MacOS ld warning: -undefined dynamic_lookup may not work with chained fixups

Getting a linker warning after upgrading to MacOS Monterey (12.6). Repro steps:

  1. Create empty Bar.hs module (module Bar where)
  2. Run ghc -shared Bar.hs 
[1 of 1] Compiling Bar              ( Bar.hs, Bar.o )
Linking a.out ...
ld: warning: -undefined dynamic_lookup may not work with chained fixups

Artifacts still seem to work, but it would be nice to resolve (or hide?) the warning.

From the man page:

     -undefined treatment
             Specifies how undefined symbols are to be treated. Options are: error, warning,
             suppress, or dynamic_lookup.  The default is error. Note: dynamic_lookup that
             depends on lazy binding will not work with chained fixups.
