You didn't really look, did you? In by binutils info page, on
(binutils)nm

    `T'
          The symbol is in the text (code) section.

                                                         If lowercase,
     the symbol is local; if uppercase, the symbol is global (external).

So the symbol is global in one case, and local in the other. That
should not be a problem, provided the linker magic for global object
construction continues to work. Since it should be an ELF target,
making the symbols local is the right thing to do.

The difference in 'g' vs 'b' is between

    `G'
          The symbol is in an initialized data section for small
          objects.  Some object file formats permit more efficient
          access to small data objects, such as a global int variable
          as opposed to a large global array.
    `B'
          The symbol is in the uninitialized data section (known as
          BSS).

so that should not matter, either. Also asso_values.8464 is a
synthetic name indicating generated for a local variable; the
numbering may have changed for some reason, but it should not be
relevant (unless the function is inline).

Why do you need to resolve them?

Anyway, coming back to my earlier point: You really should recompile
all those libraries, as nobody will give you a guarantee that they
continue to work even if you manage to link them.
