* THE RULES for all the stuff the linker creates --
*
* GOT Entries created in response to LTOFF or LTOFF_FPTR
* relocations. Dynamic relocs created for dynamic
* symbols in an application; REL relocs for locals
* in a shared library.
*
* FPTR The canonical function descriptor. Created for local
* symbols in applications. Descriptors for dynamic symbols
* and local symbols in shared libraries are created by
* ld.so. Thus there are no dynamic relocs against these
* objects. The FPTR relocs for such _are_ passed through
* to the dynamic relocation tables.
*
* FULL_PLT Created for a PCREL21B relocation against a dynamic symbol.
* Requires the creation of a PLTOFF entry. This does not
* require any dynamic relocations.
*
* PLTOFF Created by PLTOFF relocations. For local symbols, this
* is an alternate function descriptor, and in shared libraries
* requires two REL relocations. Note that this cannot be
* transformed into an FPTR relocation, since it must be in
* range of the GP. For dynamic symbols, this is a function
* descriptor for a MIN_PLT entry, and requires one IPLT reloc.
*
* MIN_PLT Created by PLTOFF entries against dynamic symbols. This
* does not reqire dynamic relocations.
