According to the upstream changelog this has been done intentionally:
* uses gcc -march=native on more architectures where available, and
correctly set arch flag in CXXFLAGS not CFLAGS
-march=native is not appropriate for distro packaging as it makes the results
of the build dependent on what CPU happens to be in the build machine and
means that the resulting binaries are unlikely to work on the minimum CPU
supported for the port.
Do you see any current issues with this setting or is it just a future
problem that might arise?
