-march=native does not always work when trying to build mit-scheme-c-9.2. On a Skylake iMac, a successful workaround is to set anything from -march=core2 up to -march=ivybridge. -march=haswell and -march=native fail, so this seems to be a haswell-and-up specific problem.

The error looks like this:
