      "Illegal instruction" happens, when executing mongod on CentOS 7 on a system with Ivy Bridge CPU.

      The issue seems similar to: https://jira.mongodb.org/browse/MONGOSH-1604

      Attached is cpuinfo and gdb output of: gdb -ex run -ex bt -ex 'disassemble $rip-100,$rip+100' --batch --args mongod

      Since we're running a lot of microservers with this generation of CPUs, the support of it is important to us.
