Comment (by kencu):

 Yes, until someone finally sorts out "driverdriver.c" you would have to
 set the build up to call the x86_64 gfortran compiler  directly (ie not
 via the main gfortran-mp-12 file but via the direct x86_64_gfortran-mp-12
 compiler) using the muniversal portgroup and some direct calls like you
 did in gcc10-bootstrap to build universal.
