Can we take a step back, because I think I lost the plot, sorry.

Why are we going through all this?

So with this when something is build as 32bit it can use 64bit as
"native" pointer size. Or if something is cross compiled to
little-endian it can still report big-endian as "native",

But when does that ever make sense?  Why would one run the 32bit
binary on a 64bit system and wanting the default -p native be 64bit
instead of 32bit? Wouldn't one install and run the actual "native"
64-bit binary in that case?
