[PATCH v8 11/11] target/arm: gdbstub: Guard pauth code with CONFIG_TCG

[Fabiano Rosas]

We currently don't have the reading of pauth regs implemented for KVM
so wrap the pauth registration with CONFIG_TCG.

This avoids the build error when using --disable-tcg:

libqemu-aarch64-softmmu.fa.p/target_arm_gdbstub64.c.o: in function
`aarch64_gdb_get_pauth_reg': ../target/arm/gdbstub64.c:233: undefined
reference to `pauth_ptr_mask'

Does this make sense? I seem to remember we had a rule that for KVM
register values should come from the ONE_REG interface.
