Thanks for the encouragement.  Looks like libstdc++-v3/configure
is setting SYMVER_MAP=config/linker-map.dummy because it sees that
no libgcc_s.so was generated; configure says
checking for shared libgcc... no.
This happened even though I ran gcc's configure with --enable-shared!

This looks vaguely similar to something from two years ago:

I'm hoping that one of the two patches
gcc-20030210-sh-linux-1.patch
gcc-3.2.3-sh-linux-dwarf2-1.patch
from
http://mirror.sh-linux.org/rpm-2003/SRPMS/gcc-3.2.3-3.src.rpm
make this go away.  (Looks like those are mostly very simple, important
fixes in those patches for sh, along with a couple patches that
touch generic code and may or may not be safe for other architectures...)
I'm building now with those two patches to see.
