OpenBIOS qemu-ppc build with symbols

GDB crashes when loading the symbols from the attached binary, which is the
qemu-ppc build of openbios.

I'm using this toolchain from builtroot:
https://toolchains.bootlin.com/downloads/releases/toolchains/powerpc
64le-power8/tarballs/powerpc64le-power8--glibc--bleeding-edge-2021.11-2.tar=
.bz2

To reproduce the issue, run the following command:
./powerpc64le-power8--glibc--bleeding-edge-2021.11-2/bin/powerpc64le-buildr=
oot-linux-gnu-gdb
-ex 'set verbose on' -ex 'set debug symfile on' -ex 'set debug symtab-create
99' -ex "symbol-file $PWD/openbios-qemu.elf.nostrip"

The last few lines of output, which give a clue to the issue are:

Recording minsym:  mst_text                       0xfff33824     1  escc_in=
