other than SHT_PROGBITS/SHT_NOBITS and neither for .got/.got.plt/.plt
created by the linker nor !SHF_ALLOC.
* elf32-i386.c (elf_i386_finish_dynamic_sections): Point
DT_PLTGOT to the start of the .got.plt section instead of the
.got output section. Set sh_entsize for .got section in addition
to .got.plt.
