Remove Unncessary Symbols

[hohle]

Cleans up symbols that are now determined at compile or link time and no longer references from ASM.

I am not at home to verify this. But you might need to add g_ServantDesc to the undefined symbol list in config/ as the linker needs to resolve its address

I got a little ahead of myself on the first push. The format of symbols.$VERSION.$OVERLAY.txt seems to need to be compatible with both splat and ld, but ld doesn't like modern single line comments.

Moving the symbols to the undefined_syms file worked out and may be a great place for overlay boundary symbols.

Conflicts need to be resolved, but it looks good to me!
