Using gcc for linking should be fine. Sounds to me like you have some
odd flags coming from somewhere or some asm with V9 specifics (you don't
get a SPARCPLUS V8+ binary using -mv8plus, it's what you see when you
compile with -mv9). So, I am assuming that you might be getting a
sparc64 compilation environment (did you say you were compiling on an
ultrasparc?).
Try compiling with the sparc32 command ("sparc32 make all"), which
should fake the build into thinking sparc-linux, instead of
sparc64-linux.
