I was thinking that a bunch of relocs to the same symbol would resolve
faster than relocs to different symbols; perhaps that's not the case.
No, it isn't. Each reloc contains a symbol index. When the linker
performs the relocations, it first computes a table of all the symbol
values; the linker must perform this operation anyhow in order to
generate the symbol table of the output file. Then the linker loops
through the relocs, resolving them. Calculating the value of a symbol
is just a table lookup.
