Yeah, I'm looking forward to being able to compile this way:

-march=x86-64 -mextra-arch=x86-64-v3

And do _nothing_ else and get a single binary. And then at runtime the
appropriate code for the detected uArch gets executed.

To make it simple Linux distros seemingly want to be able to compile a single
binary (application or shared library) which has two distinct code paths for
different flavours of the x86-64 arch to extract maximum performance from it
regardless of the CPU it's being executed on.
