Set mcpu instead of march on ARM #148

Closed IanButterworth closed 4 years ago

IanButterworth commented 4 years ago

As per https://community.arm.com/developer/tools-software/tools/b/tools-software-ides-blog/posts/compiler-flags-across-architectures-march-mtune-and-mcpu

You must use -mcpu for Arm and -march for x86

It seems to make sense to switch the ARM buildbots to use mcpu instead of march

I'm preparing a PR but thought I'd create an issue to link to in a code comment

Closing this in favor of the ARM pull request where Yichao is dispensing wisdom: https://github.com/JuliaCI/julia-buildbot/pull/151
