linuxkm/Makefile: in recipe (awk script) for wc_linuxkm_pie_reloc_tab.c, report and error on unexpected relocation types;
linuxkm/module_hooks.c: in wc_linuxkm_normalize_relocations():
* fix bounds checking on the input,
* recognize references pointing at the first byte after the end of the segment,
* and mask out pad bytes when rendering the 32 bit addresses;
linuxkm/wolfcrypt.lds: add 4k alignment directives just before the segment end fenceposts, to make the fenceposts more inclusive.
