When configured with --enable-debug, the makefile does not use any
optimization and compilation of hw/ppce500_mpc8544ds.c fails because gcc
does not remove the never called without kvm function
mpc8544_copy_soc_cell(), which will fail to link without the kvm code.
I'm not sure I can follow. So the problem is that we call
kvmppc_read_host_property and don't provide a stub wrapper for it? Let's
provide a wrapper then instead of crippling the target code :)
The problems exists only with --disable-kvm and --enable-debug. Without
--enable-debug, qemu is compiled with -O2, gcc detects that
kvm_enabled() always returns false and optimizes out
mpc8544_copy_soc_cell calls which will not be called anyway. With
--enable-debug, the linker cannot find symbols which it won't call anyway.
