Then should we follow option (1) not further support pre-v9 sparc? If so, much the same approach should be followed as for i386: make configure give an error when the compiler is configured for pre-v9; merge sysdeps directories so there are no longer separate sparcv8 and sparcv9 subdirectories but sparc/sparc32 assumes v9; remove obsolete preprocessor conditionals such as in kernel-features.h.
Possibly we should retain a place for Leon3, which is mostly v8 but adds the casa instruction and the ability to use #ASI_USER_DATA from userspace.
