It looks so:

$ grep '  set_gdbarch_process_record ' gdb/*
amd64-linux-tdep.c:  set_gdbarch_process_record (gdbarch, i386_process_record);
arm-linux-tdep.c:  set_gdbarch_process_record (gdbarch, arm_process_record);
i386-linux-tdep.c:  set_gdbarch_process_record (gdbarch, i386_process_record);
moxie-tdep.c:  set_gdbarch_process_record (gdbarch, moxie_process_record);

But the OS dependent part seems to be missing there:
arm-tdep.h:
   /* Parse swi insn args, sycall record.  */
  int (*arm_swi_record) (struct regcache *regcache);
 - which does not seem to be set anywhere
 
So the current set_gdbarch_process_record initialization could be possibly
moved to arm-tdep.c.  But I did not play more with it.
