Question about LSAN sanitizer on AARCH64

Hi everyone,

I have question about LSAN sanitizer on aarch64 architecture. Why make check-lsan is not enabled?
When I enable it some tests fail. Part of them fail because of different printing of pointers (etc libc
fprintf prints 0x7f79003c80 and LSAN print prints 0x007f79003c80 and when make check checks those values test fails).
Some of the tests fail when using thread local storage option (use_tls=1).
Does anyone know something more about this issues ?

Regards,

Copying Adhemerval, as he is the one adding sanitizer support to AArch64.
