Bug#840165: fcl builds on amd64 with -march=native

[Adrian Bunk]

Source: fcl
Version: 0.5.0-4
Severity: grave

CMakeLists.txt sets -march=native in amd64 builds.

This means the code will only run on machines with a CPU
compatible with the one on the machine where the package
was built.

Building on a different buildd machine can also change
where the code can run - including breaking existing
setups in stable updates.

Please remove -march=native from CMakeLists.txt
