// requires GOT entries and correspondingly ordered dynamic symbol table
// entries to deal with dynamic relocations. To handle this problem
// relocation-only section in the primary GOT contains entries for all
// symbols referenced in global parts of secondary GOTs. Although the sum
// of local and normal global entries of the primary got should be less
// than 64K, the size of the primary got (including relocation-only entries
// can be greater than 64K, because parts of the primary got that overflow
