      The switch over to v5 toolchain (WT-14127) caused all workgen tests to fail on ARMV9. The tests all seg fault at the line:

      (gdb) f 0
#0  workgen::OptionsList::add_int (this=this@entry=0xfffff6cb7740 <workgen::ParetoOptions::DEFAULT+24>, name=..., default_value=<optimized out>, default_value@entry=0, desc=...) at /home/ec2-user/wiredtiger/bench/workgen/workgen.cpp:837
837	    sstm << "int, default=" << default_value;
