As I have a similar problem with gmic, here is my workaround in debian/rules,
maybe its helpful for you:

BUILDD_MEM := $(shell awk '/^MemTotal:/ {print $$2}' /proc/meminfo)
BUILDD_MEM_OK := $(strip $(shell test $(BUILDD_MEM) -gt 1800000 && echo yes))

BUILDD_SLOW_ARCH := $(strip $(shell dpkg-architecture -qDEB_BUILD_ARCH_CPU | \
                           grep -q -E '^(arm|mips|sh4|m68k).*' && echo yes))

ifneq (yes,$(BUILDD_MEM_OK))
  GMIC_CFLAGS = -O0 -g
else
  ifneq (yes,$(BUILDD_SLOW_ARCH))
    GMIC_CFLAGS = -O3 -g
  else
    GMIC_CFLAGS = -O1 -g -fno-tree-pre
  endif
endif

Good luck,

Bernd
