compiler-gcc: disable -ftracer for __noclone functions
commit 95272c29378ee7dc15f43fa2758cb28a5913a06d upstream.
-ftracer can duplicate asm blocks causing compilation to fail in
noclone functions. For example, KVM declares a global variable
in an asm like
asm("2: ... \n
.pushsection data \n
.global vmx_return \n
vmx_return: .long 2b");
and -ftracer causes a double declaration.
