The AIX build fails after 8257602 with the error :
./src/hotspot/share/gc/shared/allocTracer.cpp:35:8: error: unknown type name 'THREAD_LOCAL'
static THREAD_LOCAL int64_t _last_allocated_bytes = 0;

    const size_t weight = allocated_bytes - _last_allocated_bytes;

    _last_allocated_bytes = allocated_bytes;


Probably we should not build that JFR only (?) codinf because JFR is not supported on AIX.
Additionally the THREAD_LOCAL macro is not defined at the moment on AIX/xlc.
