Dirk Mueller 366ef06a7b - add glibc-io-Do-not-implement-fstat-with-fstatat.diff
- add glibc-getaddrinfo-fix-use-after-free-in-getcanonname.patch
  (bsc#1215281, CVE-2023-4806)
- Regenerate it also in the %post of glibc-local-base-<targettype>
  But to create clearly defined bootstrap projects, it's essential
- Recognize ppc64p7 arch to build for power7
- add ld-linux.so.3 compat symlink also for armv6hl
- Do not order nscd after syslog.target
  * bugfixes
- Update manpages from Debian, includes new man pages for
- Use _target_cpu instead of _build and _host. This makes the
- check-build.sh: accept kernel 3.x
  - more libm optimizations
- Revert last change, it caused some breakage. [bnc#715854]
  for vsyscall which is not anymore in 3.1 kernel
- Further cleanup of ld.so.conf to remove duplicate directories
- Fix warning about potential array subscript out of bounds
- Work around shortest-stem feature in make 3.82+ (patch
- Update to glibc-2.10.1-e38af591a8 of glibc/pb-stable.git glibc-2.10-branch
- only do obsoletes for XXbit packages on ppc, not on x86
  * Fix sched_getcpu error path on x86-64.
- nptl/init.c (sigcancel_handler): Compare with correct PID even
- Don't terminate strings twice in nis/netgroup code.
- Fix invalidating of nscd caches and getaddrinfo()
- Update to current CVS:
- Update to current CVS version and update to
- Add fixes from CVS:
- forward umount to umount2 on ppc64 because umount syscall
- really fix linux/percpu.h to compile in userland
- Update to kernel header files from 2.6.0-test7
