Sam Ravnborg b5db854a91 sparc,sparc64: unify asm-offsets.c
sparc64 does not use constants generated from asm-offsets
but to prepare it to do so the parts that could be
shared do now generate constants for sparc64 too.

/*
* This program is used to generate definitions needed by
* assembly language modules.
*
* We use the technique used in the OSF Mach kernel code:
* generate asm statements containing #defines,
* compile this file to assembler, and then extract the
* #defines from the assembly-language output.
*
* On sparc, thread_info data is static and TI_XXX offsets are computed by hand.
