[#MDEV-5413] kvm-fulltest2 fails on 5.3 because BUILD/compile-pentium-debug-max with -O2 does not work

kvm-fulltest2 always fails on 5.3 tree at the compilation stage. It attempts to build the server as

EXTRA_FLAGS="-O2 -Wuninitialized -DFORCE_INIT_OF_VARS" EXTRA_CONFIGS="--with-embedded-privilege-control" AM_EXTRA_MAKEFLAGS="VERBOSE=1" BUILD/compile-pentium-debug-max

In buildbot it fails with

In file included from /usr/include/string.h:642:0,

                 from ../include/m_string.h:32,

                 from mysql_priv.h:47,

On my machine it failed with

client.c:2952:7: error: comparison of unsigned expression < 0 is always false [-Werror=type-limits]

Either way, it never makes it through the build. I don't know if this build variant is important enough to fix it, but if not, I suggest to disable the test for 5.3 tree – it is 20 minutes per push which we do not need to waste.

I can do it in buildbot, I just need confirmation that the build is not going to be fixed.

Alternatively, we can remove "-O2" from the flags.
