if this is only used for MIPS, it maybe worth to discuss it a little more in a
comment

The dynamic symbol table is divided into local and global parts. The global part
of the dynamic symbol table is further divided into two parts: symbols that do
not have GOT entries associated with them and symbols that do have GOT entries
associated with them. This is index of the first global symbol that has .got
entry.
