I'm not sure if you are referring to the difference between host/target
architecture. (Indeed, I suppose host should be replaced by target
architecture. I'm simply not used to thinking about cross-compiling.)

Alternatively, regarding the issue of i386 vs. x86_64: I'm running
Debian i386 userland with an amd64 kernel on x86_64 hardware. The
autoconf macro detected my host architecture as x86_64 and thus could
not find my native i386 boost libraries.

My patch is meant to fix precisely this issue by searching for i386 as a
fallback when x86_64 is detected, but maybe I'm doing it the wrong way
and there is a method to detect the userland architecture?
