Oh wow, we dropped RHEL/CentOS 6 support a very long time ago for QEMU,
and also dropped RHEL-7 last year.

FWIW, our platform target policy is set out here:

   https://www.qemu.org/docs/master/about/build-platforms.html

Currently RHEL-8 is the oldest RHEL we support since RHEL-7
also dropped out under the rule

  "Support for the previous major version will be dropped
   2 years after the new major version is released"

I'm surprised you didn't have to patch lots of other aspects of QEMU,
since a system targetting glibc 2.12 would be likely to have a GCC
version that we explicitly block use of at build time, as well as
other outdated 3rd party libraries we check min versions of in
configure.

Daniel
