This is a known fact admitted by upstream.  I even failed to build on
not so powerfully RAM equiped amd64 machines.  The only solution I see
is to exclude all other architectures than the one you are mentioning
above.

It seems reducing optimisation in d/rules

DEB_HOST_ARCH       ?= $(shell dpkg-architecture -qDEB_HOST_ARCH)
DEB_BUILD_ARCH_BITS := $(shell dpkg-architecture -qDEB_BUILD_ARCH_BITS)
ifeq ($(DEB_BUILD_ARCH_BITS),32)
    CFLAGS=$(shell dpkg-buildflags --get CFLAGS | sed 's/-O[2-9]/-O1/')
    CXXFLAGS=$(shell dpkg-buildflags --get CXXFLAGS | sed 's/-O[2-9]/-O1/')
endif


did not really help (perhaps even droping -O1 could be tried but I
doubt this).

Kind regards

        Andreas.
