Ah, it was a moment of no coffee.  Here it is:
# /compat/linux/bin/sh /usr/bin/ldd /usr/local/share/linux-ut/System/ut-bin
         not a dynamic executable

The native ldd works better:
# ldd /usr/local/share/linux-ut/System/ut-bin
         libdl.so.2 => /lib/libdl.so.2 (0x2807a000)
         libnsl.so.1 => /lib/libnsl.so.1 (0x28080000)
         libpthread.so.0 => /lib/libpthread.so.0 (0x28099000)
         Engine.so => not found
         Core.so => not found
         libSDL-1.1.so.0 => /usr/lib/libSDL-1.1.so.0 (0x280b1000)
         libm.so.6 => /lib/libm.so.6 (0x28138000)
         libc.so.6 => /lib/libc.so.6 (0x28161000)
         /lib/ld-linux.so.2 (0x2805a000)
