prelink: Fix Segmentation fault error when prelink qemurbt/prelink
The info->resolvetls might be NULL according to src/prelink.c: [snip] /* Dynamic linker does not depend on any other library, all symbols resolve to themselves with the exception of SHN_UNDEF symbols which resolve to 0. */ if (info->symtab[r_sym].st_shndx == SHN_UNDEF) { info->resolveent = NULL; info->resolvetls = NULL; [snip] So we must check it before use its members, otherwise, there might be Segmentation fault error. Fixed: MACHINE = "qemumips" IMAGE_INSTALL_append = " qemu" $ bitbake core-image-minimal [snip] | /path/to/qemumips-poky-linux/core-image-minimal/1.0-r0/temp/run.prelink_image.1000: line 111: 1010 Segmentation fault (core dumped) [snip] Signed-off-by: Robert Yang <liezhi.yang@windriver.com>
