You could try forcing altivec off in libjpegturbo by setting the environment:
export JSIMD_FORCENONE=1
that works! Once set, the application loads several JPG files without
issues.
If that helps, then something is wrong with the runtime detection code.
It appears it is supposed to detect if the CPU supports altivec at
runtime and only use it if it is there.
I suppose that is the case then. Good to confirm that it is not a
GNUstep issue...

Could you ask gdb what the illegal instruction is?
how would I do that?
I tried:
(gdb) disassemble
No function contains program counter for selected frame
