sparc: Use 64BIT config entry 

Use 64BIT config entry to distinguish between 32 and 64bit builds
instead of relying on the ARCH setting.  Using sparc64 as ARCH still
forces 64BIT on.

Inspired by the x86 and s390 configs.

[ Integrated CONFIG_64BIT help text suggestions from Sam -DaveM ]

SPARC is a family of RISC microprocessors designed and marketed by
Sun Microsystems, incorporated. They are very widely found in Sun
workstations and clones. This port covers the original 32-bit SPARC;
it is old and stable and usually considered one of the "big three"
along with the Intel and Alpha ports. The UltraLinux project
maintains both the SPARC32 and SPARC64 ports; its web page is
available at <http://www.ultralinux.org/>.
