From the InnoDB developers: UNIV_PFS_MUTEX and UNIV_PFS_RWLOCK: Defined whenever the server is compiled with the -DWITH_PERFSCHEMA_STORAGE_ENGINE option. PFS_GROUP_BUFFER_SYNC: Disabled by default. The only way to enable it is by removing the line which defines PFS_SKIP_BUFFER_MUTEX_RWLOCK in storage/innobase/include/sync0sync.h. Seems to be no compiler flags to enable or disable the above mentioned symbol.
