We see Perf failing to compile on: arm, arm64, i386, x86_64, under OpenEmbedded (GCC 11.3) when building for the following machines:
* Dragonboard 410c (arm64)
* Dragonboard 845c (arm64)
* Juno (arm64)
* X15 (arm)
* intel-core2-32 (i386)
* intel-corei7-64 (x86_64)

Additionally, we see this same problem outside of OpenEmbedded but only on arm (32-bits), because in all other cases it fails to build at an earlier point with the already reported problem of init_disassemble_info() [1][2], so it's very likely to be there too on all architectures.
