A cross-architecture build might pass a target-specific CC on 'make', and not on 'make install', and this is what happens in Debian cross-qa tests.

Given that we select binaries to be installed depending on the target architecture, this means we would build AVX2 binaries in any case on a x86_64 build machine.

By overriding TARGET in package build rules, we can tell the Makefile about the target architecture, also for the 'install' (Makefile) target.
