Why limit the fixes to Tier2 archs? -march=native is not allowed outside
of MANUAL_PACKAGE_BUILD even for i386/amd64 to avoid a random package
cluster machine being the lowest common denominator for CPU support.
-mtune=native on arm *probably* has the same implications as
-march=native on x86.

What's the intent here?
