The 32-bit PPC auxv is a bit complicated because in the
mists of time it used to be 16-aligned rather than directly
after the environment. Older glibc versions had code to
try to probe for whether it needed alignment or not:
https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/unix/sysv/linux/powerpc/dl-sysdep.c;hb=e84eabb3871c9b39e59323bf3f6b98c2ca9d1cd0
and the kernel has code which puts some magic entries at
the bottom to ensure that the alignment probe fails:

QEMU has similar code too, but it was broken by commit
