OK, I ran  

find . -exec grep -Hn -e '__sparc_v9__' {} \;

in xsrc/xfree, most files that test for '__sparc_v9__' macro are under
xsrc/xfree/xc/extras/Mesa If they assume that __sparc_v9__ implies __arch64__
then the fix could be as easy as changing one macro to the other But then I
don't know much about XFree86 and it's build system, so I could be wrong...
