Robert Yang 1faa551931 elfutils: check data_list.data.d.d_buf before free it
[YOCTO #12791]

The one which actually saves the data is data_list.data.d.d_buf, so check it
before free rawdata_base.

This can fix a segmentation fault when prelink libqb_1.0.3:
prelink: /usr/lib/libqb.so.0.18.2: Symbol section index outside of section numbers

The segmentation fault happens when prelink call elf_end().

Fixed:
MACHINE="qemux86-64"
IMAGE_INSTALL_append = " libqb" #libqp is from meta-openembedded
$ bitbake core-image-minimal
Segmention fault

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
