New x86-64 micro-architecture levels
Most Linux distributions still compile against the original x86-64
baseline that was based on the AMD K8 (minus the 3DNow! parts, for Intel
EM64T compatibility).
There has been an attempt to use the existing AT_PLATFORM-based loading
mechanism in the glibc dynamic linker to enable a selection of optimized
libraries. But the general selection mechanism in glibc is problematic:
