  Checking if glibc still builds with the minimum advertised gcc version
showed some issues, which are easily fixed.  There are some issues that
are not easily fixed that either would require GCC backports to old
releases (like ia64 GPREL22 overflows issues again __dso_handle),
a large backport on old glibc releases (riscv R_RISCV_GPREL_I relocation
against __ehdr_start that was fixed by a code refactor only presented
in 2.35), or large compiler backports (like for arc that prevented build
with gcc older than 9).

Adhemerval Zanella (3):
  malloc: Fix set-freeres.c with gcc 6
  sunrpc: Fix netname build with older gcc
  powerpc: Fix powerpc64 strchrnul build with old gcc

It would be great to still have this in the release.

That said, I can't technically judge it, so a second OK would be nice.

We can always backport it since it should only affect old compilers.
