[PATCH] LoongArch: fix .got.plt dislocation in static PDE
This patch addresses a bug in the LoongArch ELF linker where the calculation of .got.plt entry addresses was incorrect for static Position-Dependent Executables (PDE). The code incorrectly assumed the presence of two .got.plt entries reserved for ld.so, which do not exist in static PDE, leading to a two-slot dislocation of all .got.plt entries. This error, latent in earlier releases, became exploitable in 2.47.
