This is a bad suggestion and was apparently made without referring to the
existing Debian instructions for how to handle packages that use Autoconf
and friends. Please see the autotools-dev instructions, which are more
detailed and which correctly recommend:
DEB_HOST_GNU_TYPE ?= $(shell dpkg-architecture -qDEB_HOST_GNU_TYPE)
DEB_BUILD_GNU_TYPE ?= $(shell dpkg-architecture -qDEB_BUILD_GNU_TYPE)
ifeq ($(DEB_BUILD_GNU_TYPE),$(DEB_HOST_GNU_TYPE))
SYSTEM = --build $(DEB_HOST_GNU_TYPE)
else
SYSTEM = --build $(DEB_BUILD_GNU_TYPE) --host $(DEB_HOST_GNU_TYPE)
endif
# ...
./configure $(SYSTEM)
