Build fails because 32 bit absolute addressing isn't supported

[MarcusJohnson91]

I'm on OS X, just did a fresh clone of the repo, and clang outputs the following when calling make.

I'm currently using the beta of Xcode 8, but this issue has been ongoing for a while.

make CFLAGS="-march=native -ofast" LDFLAGS="-flto"

I suspect the issue is in fullbench. It contains some externally supplied experimental code, which is usually not compiled because it's behind a macro condition. -march likely trigger some of them.

I'll make a cleaning a the near future.

[MarcusJohnson91]

I just tested it again by running make and that issue didn't appear, so it seems like -march=native probably was the cause.

[Cyan4973]

I removed a bunch of experimental codes from fullbench, so I guess it should work better with -march=native enabled now.

[MarcusJohnson91]

That fixed it, thank you.
