[Debian-med-packaging] Bug#973977: centrifuge FTCBFS: uses uname for bits detection

[Helmut Grohne]

Source: centrifuge
Version: 1.0.3-6
Tags: patch
User: debian-cross at lists.debian.org
Usertags: ftcbfs

centrifuge fails to cross build from source, because its Makefile
detects a -m64 flag from uname and that can happen to be the wrong
result. The attached patch passes dpkg's view of bits and generally
removes any -m64 flag unneeded on Debian toolchains. Surprisingly it
still fails to build due to narrowing conversions. I suspect that there
is a difference in the cross toolchain. Please consider applying the
attached patch and close this bug when doing so.
