Fix SPARCv8 condition
The define provided by the compiler on SPARCv8 is __sparc_v8__ and not
__sparcv8. From a SPARCv8 gcc:
$ sparc-linux-gcc --version
sparc-linux-gcc (Buildroot 2015.08-git-00497-ge110081) 4.9.3
[...]
$ sparc-linux-gcc -dM -E - < /dev/null | grep sparc
#define sparc 1
#define __sparc__ 1
#define __sparc 1
#define __sparc_v8__ 1
