[PATCH 1/9] sparc: add 'sparcv8' predefines for sparc32

[Luc Van Oostenryck <luc.vanoostenryck@xxxxxxxxx>]

By default, the architecture version is 'v8' for sparc32
and 'v9' for sparc64.
The predefines were added for sparc64 but not for sparc32.

Fix this by adding a generic 'sparcv%d' together with a
variable to hold the architecture version and initialize
this one accordingly.
