In order to support hypervisor analysis of crash dumps, xen-syms needs to contain debug_info. It should be allowed to configure the hypervisor to be built with CONFIG_DEBUG_INFO in non-debug builds without having to enable EXPERT. Using a rather oldish gcc (7.5) it was verified that code generation doesn't really differ between CONFIG_DEBUG_INFO on or off without CONFIG_DEBUG being set (only observed differences were slightly different symbol addresses, verified via "objdump -d", resulting from the different config.gz in the binary). The old gcc version selection was based on the assumption, that newer gcc won't regress in this regard. So move CONFIG_DEBUG_INFO out of the section guarded by EXPERT. It should be mentioned that there have been reports that the linking of the xen.efi might take considerably longer with CONFIG_DEBUG_INFO selected when using newer binutils.
