I have a similar issue with gmic - my workaround is to use -O0 on the
architectures where it would fail to build due to exhausted memory.

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

ifneq (,$(findstring arm,$(shell dpkg-architecture -qDEB_BUILD_GNU_CPU)))
  GMIC_CFLAGS = -g -O0
  ifneq (,$(findstring mips,$(shell dpkg-architecture -qDEB_BUILD_GNU_CPU)))
    GMIC_CFLAGS = -g -O0
    ifeq (yes,$(BUILDD_MEM_OK))
          GMIC_CFLAGS = -g -O0

Not the best solution as it means that gmic will be slow(er) on arm and mips at
least, but the only working solution.
