Is your compiler configured to define __sparcv9 when it compiles?
The following should tell you:

% touch /tmp/file.c
% gcc -dM -E /tmp/file.c | grep __sparcv9

If the output is similar to the below, you're fine:
#define __sparcv9 1

If the above command gives no output, then you need to specify -mcpu=v9
or reconfigure/recompile GCC to default to outputting V9 code.
