I'd expected this, but thought to better ask :-)  And you're certainly
right about the risk: initial testing revealed several stupid errors, and
it's not a good idea to try to hash this out under extreme pressure.

Ok, I'll follow this route.  There's only one place where it might be
necessary to still have a mixture: sparc/sol2-sld-64.h defines
SPARC_BI_ARCH depending on AS_SPARC64_FLAG, and only then includes
sparc/sol2.h.  All other sol2 config files include some other file first
thing, overriding part of it in their bodies.

Ok, fine.
