Comment (by eborisch):

 Try re-installing mpich-default (uninstall & reinstall mpich-default which
 will then re-configure & build) after Xcode 15 installation. (mpich-
 default doesn't use buildbot packages, although the buildbot is still on
 Xcode 14 so it won't help currently anyway.)

 The issue is ld from Xcode 15 rejecting `-Wl,-commons,use_dylibs`. The
 configure script for mpich correctly detects this when Xcode 15's ld is
 used, but if you configure/install mpich under Xcode 14, and then upgrade
 Xcode, the compiler scripts (mpicc, mpicxx, etc.) will still have the
 offending switch.
