--- Comment #1 from Eric Botcazou <ebotcazou at gcc dot gnu.org> ---

Bold assumption... you need do something along the lines of PR ada/56030, i.e.
modify ada/gcc-interface/Makefile.in

# Make arch match the current multilib so that the RTS selection code
# picks up the right files. For a given target this must be coherent
# with MULTILIB_DIRNAMES defined in gcc/config/target/t-*.

ifeq ($(strip $(filter-out %x86_64, $(target_cpu))),)
  ifeq ($(strip $(MULTISUBDIR)),/32)
    target_cpu:=i686
  else
    ifeq ($(strip $(MULTISUBDIR)),/x32)
      target_cpu:=x32
    endif
  endif
endif

so that target_cpu:=i686 is selected, see $(builddir)/gcc/multilib.h.
