Added ~sparc to glibc-2.3.4.20040808-r1, but it is masked in the sparc32 and sparc64 PROFILE_ARCHs.  Older versions have v9a assembly code that doesn't work with newer binutils.  Glibc also isn't quite smart enough to realize that it has v9a assembly, so if it uses the gcc default (v9), it will fail, so we force v9a as flags.  I also added the updated logic to 2.3.4.20041102, but as I haven't tested it yet, it hasn't been marked.
