vgPlain_unknown_SP_update (aka VG_(unknown_SP_update)) is just an ordinary
function in coregrind/m_stacks.c
I can't see any conditional compilation that would cause it to be not compiled.
There is this bit in coregrind/Makefile.am
# The below files cannot be compiled with lto, otherwise that gives
# undefined symbols at link time. So, define a noinst library to
# build the needed .o with specific flags.
# These objects are added to the libcoregrind library.
NOLTO_COREGRIND_SOURCES_COMMON = \
m_libcsetjmp.c \
m_main.c
Perhaps m_stacks.c needs to be moved there?
Can you check with nm that vgPlain_unknown_SP_update is in
libcoregrind-ppc64be-linux.a ?

Would it be possible to try a build with just "configure"? Or even just without
--enable-lto=yes?
