I added that when configuring my final gcc, and it helped quite a bit!
Now I'm getting:

./sh4-unknown-linux-gnu-hello2: /lib/libstdc++.so.5: version `GLIBC_2.2' not found (required by ./sh4-unknown-linux-gnu-hello2)
./sh4-unknown-linux-gnu-hello2: /lib/libstdc++.so.5: version `GLIBC_2.2' not found (required by /lib/libstdc++.so.5)
./sh4-unknown-linux-gnu-hello2: /lib/libstdc++.so.5: version `GLIBC_2.2' not found (required by /lib/libstdc++.so.5)

That seems a bit odd.  The C hello still runs fine, btw.

All I can think of is there's something fishy going
on in my chroot environment on the target.  I did
try doing a ldconfig in the chroot jail, but I guess
that was the moral equivalent of swinging a dead chicken
over my head for luck; it didn't do anything.


FWIW, let's try ldd on libstdc++.so.5
on my workstation's own copy, then on the target:

** x86 workstation **
$ ldd /usr/local/lib/libstdc++.so.5
        libm.so.6 => /lib/libm.so.6 (0x400c0000)
        libgcc_s.so.1 => /usr/local/lib/libgcc_s.so.1 (0x400e1000)
        libc.so.6 => /lib/libc.so.6 (0x400e9000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

$ objdump -p /usr/local/lib/libstdc++.so.5
...
Version References:
  required from libgcc_s.so.1:
    0x0b792650 0x00 08 GCC_3.0

    0x0d696911 0x00 07 GLIBC_2.1
    0x0d696910 0x00 06 GLIBC_2.0

** target (I'm on my workstation, but the rsh server on 11.3.4.1 is in the chroot environment) **

$ rsh 11.3.4.1 ldd  /lib/libstdc++.so.5
/lib/libstdc++.so.5: /lib/libstdc++.so.5: version `GLIBC_2.2' not found (required by /lib/libstdc++.so.5)
/lib/libstdc++.so.5: /lib/libstdc++.so.5: version `GLIBC_2.2' not found (required by /lib/libstdc++.so.5)

$ objdump -p libstdc++.so.5
...
Version References:
  required from libm.so.6:
    0x0d696912 0x00 09 GLIBC_2.2
  required from libc.so.6:

Ah, well, too late at night to think.   This is my first
attempt at testing a whole toolchain in a chroot environment,
maybe I'm just doing something wrong.
