This isn't really important in this case, because there are no non-Linux ports
of arm, m68k or hppa, but it should be noted that the correct way to do this
portably would be:
GCC4_ICES_HERE := arm m68k hppa
DEB_HOST_ARCH_CPU ?= $(shell dpkg-architecture -qDEB_HOST_ARCH_CPU)
ifneq (,$(filter $(DEB_HOST_ARCH_CPU),$(GCC4_ICES_HERE)))
export CC=gcc-3.4
export CPP=cpp-3.4
export CXX=g++-3.4
endif
Note1: as for Build-Depends line, this can't be done portably as of now, but
pending changes in dpkg will allow it soon.
Note2: s/BUILD/HOST/g change was done not to break cross buildability
Note3: s/findstring/filter/g change prevents unwanted sub-string matching
