Thomas Petazzoni eeace1cc13 arch/Config.in.x86: add support for x86-64-v2, x86-64-v3, x86-64-v4 ... In the face of the vast amount of x86-64 CPU architecture variants, Linux distributions have worked together to define "micro-architecture levels" in the x86-64 psABI, called x86-64-v2, x86-64-v3 and x86-64-v4. They standardize a set of CPU features, and GCC since its version 11.x has support for these micro-architecture levels as -march= options. It makes sense to support them in Buildroot, especially for those who want to build toolchains that aim at targeting a reasonably broad family of x86-64 processors. It only really makes sense to use as 64-bit CPUs, and not as 32-bit ones, so we guard them behind BR2_x86_64.
