I think you are confusing build and host again.

If you check DEB_BUILD_ARCH, then you will pass -Wl,--no-relax when
building for amd64 on alpha. Since --no-relax is machine-dependent, that
seems wrong to me. In general, changing the build architecture should
not affect the resulting binary packages. Passing different flags for
different build architectures often breaks that.
