Issue number:
#3170

Description of changes:

Housekeeping changes:

  • Drop post-release patches for glibc 2.37, and add patches for 2.38.
  • Keep the localedef hack working with one more hack.
  • Remove unsupported configure options, and add new ones to disable
    building nscd rather than just excluding it from packaged files.
  • Include libmvec for all architectures, since it's now supported on
    aarch64.

Functional changes:

  • --enable-multi-arch to include microarch-optimized functions in
    the same DSO. This trades off a small amount of disk space and RAM
    to provide optimized versions of some string and memory functions.
    (This feature was disabled by accident in the original packaging.)
  • --enable-fortify-source to build with the maximum supported level
    of _FORTIFY_SOURCE when possible. Currently, this is "2", but
    will be "3" when we update to GCC 12.

Testing done:
Tested AWS and VMware variants, with this change alone and in combination with other recent commits. Nodes all came up healthy and ran containers.

Did a quick sanity check. Built an aws-k8s-1.27 variant and joined to an EKS cluster. Node joined and reported healthy. All kube-system pods looked good and were in a Running state. Ran sonobuoy quick test which passed.

Nothing stood out as odd or obviously wrong in the updated patches. Looks good to me.
