It is. You *get* the characteristics of the machine you are compiling
on [1]. You *want* the characteristics of the machine your compiled stuff
is supposed to be run.

There is no simple solution to this problem, IMHO, short of...
say building a `probe' program you send to the target machine
to collect characteristics and `bring them back' to the compilation
host.

Does auto-* have such a thing?

[1] To be more precise ...the machine you are running configure on.
