  Benefits of the solution:
  
  By having fix mmbuildgpl will successfully run on
  SLES 15.3 kernel 5.3.18-150300.59.90-default or later.
  
  Work around:
  Clear KBUILD_BUILTIN macro inside
  /usr/lpp/mmfs/src/gpl-linux/Kbuild
  
  KBUILD_BUILTIN :=
  This can be done after below surrounding code
  #For s390x: -pg and -fomit-frame-pointer are incompatible
  ifeq ($(ARCH),s390)
  ifdef CONFIG_FUNCTION_TRACER
  ORIG_CFLAGS := $(KBUILD_CFLAGS)
  KBUILD_CFLAGS = $(subst -pg,,$(ORIG_CFLAGS))
  endif
  endif
  KBUILD_BUILTIN :=
  
  Problem trigger:
  mmbuildgpl will fail on SLES 15.3 when kernel
  is upgraded to 5.3.18-150300.59.90-default or later.
  Symptom:
