--- Comment #14 from Jakub Jelinek <jakub at gcc dot gnu.org> --- We require GNU make, so one can use something like: unwind-arm.o unwind-c.o libunwind.o pr-support.o: CFLAGS += -mfpu=none or similar in libgcc/config/arm/t-arm (or similar) with a comment explaining the reason. For eh_personality.o that needs to be done elsewhere and there are no such makefile fragments (and libtool is used).
