My motivation for doing this is that for my Ghidra import to work I need more files to be temporarily marked as Matching so that additional detailed symbol info is included in the linked executable I dump from. But many of these externed symbols cause linking to fail when it would otherwise succeed. I don't think there's any remaining need to keep these things externed now that we have objdiff to work with so I've done the following:
Un-extern various floats, placing them directly inline in the source code and fixing them to be bit-accurate where appropriate (they didn't match the purported value in the comment in the last digit in some cases).
Un-extern various local / global variables, placing them in the appropriate part of the data section depending on whether they're zero initialized, uninitialized, or initialized with a value.
Make various externed string constants static so that they don't conflict if the files they're in are changed to Matching in configure.py.
