x86 setup: correct segfault in generation of 32-bit reloc kernel
Impact: segfault on build of a 32-bit relocatable kernel When converting arch/x86/boot/compressed/relocs.c to support unlimited sections, the computation of sym_strtab in walk_relocs() was done incorrectly. This causes a segfault for some people when building the relocatable 32-bit kernel. Pointed out by Anonymous <pageexec@freemail.hu>. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
