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
