Define and fill machine-specific DT_88K_PLT{START,END} _DYNAMIC tags when
creating objects with a .plt (either shared libraries or dynamic binaries).
These tags contain the start and end address of the plt, relative to the
beginning of the object.
This will (eventually) allow ld.so to find the area spanned by the plt more
easily, and also matches what SVR4/m88k does.
