I've poked around a bit more. qemu-i386 running on an i386 host[1]
seems to be fine, so that would point to a ppc-specific problem. The
address causing the fault is within the 32MB originally mmap()ed for the
ELF interpreter, but never used (so it's still PROT_NONE).
In case it's relevant, this is with GNU libc 2.2.5 (identical library
and ELF interpreter on the PPC and i386 hosts).
[1] with USE_CODE_COPY disabled, as otherwise gcc-3.0 complains at
assembler arguments
