The same issue is not encoutered when building with gcc 11.4 or later, where the compiler automatically adds the option "-mno-block-ops-vector-pair" when building for power10 which is intended as a code optimization and also effectively avoids the compiler bug displayed. Modify the meson.build file for ppc and manually set the flag when building for power10 with gcc less than 11.4.
