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.
