Now we made sure all helpers and helper_info are defined and used using HELPER/HELPER_INFO macros, we are ready to introduce a target prefix. We can't reuse TARGET_ARCH since it's not defined for common code, and it's also poisoned. So introduce a new TARGET_ARCH_PREFIX which is defined for all target code (whether it's common or target specific), and use it as prefix. On some hosts (found it on sparc), predefined macros exist for the base architecture names we use, and their value is 1. (#define sparc 1). So, we can't use them directly or it would create a illformed identifier for function names. So to prevent any problem, use additional "target", which gives -DTARGET_ARCH_PREFIX=target_<TARGET_ARCH>. Finally there is one last catch: beyond target helpers, tcg also has common helpers. For those ones, we want an empty prefix, since they are defined on tcg side and not target side. With this, we now have target prefixed helpers, preventing symbol conflicts when linking targets together.
