Please provide me with a properly tested patch that actually makes
sense.
So what should this patch look like? It is just:
export DEB_BUILD_GNU_TYPE ?= $(shell dpkg-architecture -qDEB_HOST_GNU_TYPE)
export CC=$(DEB_HOST_GNU_TYPE)-gcc
This assumes that the compiler is going to be gcc. But there are
other compilers than gcc.
As far as I know, what really should happen is that you either
set the CROSS_COMPILE environment or pass --cross-compile-prefix
to Configure so that tools like nm also get the version for the
host architecture.
So this might work:
export CROSS_COMPILE ?= $(shell dpkg-architecture -qDEB_HOST_GNU_TYPE)-
But then it actually fails with:
make[2]: x86_64-linux-gnu-ar: Command not found
So maybe it should be:
DEB_HOST_GNU_TYPE=$(shell dpkg-architecture -qDEB_HOST_GNU_TYPE)
DEB_BUILD_GNU_TYPE=$(shell dpkg-architecture -qDEB_BUILD_GNU_TYPE)
ifneq ($(DEB_HOST_GNU_TYPE),$(DEB_BUILD_GNU_TYPE))
export CROSS_COMPILE ?= $(DEB_HOST_GNU_TYPE)-
endif
But then you might not like that it's doing something different when
cross compiling, and I don't have a test environment to check
that this actually works.
