I'm still waiting for _ANY_ kind of response here.
Doesn't anyone know or care about config.guess or config.sub anymore?
From automake manual:
config.guess config.sub
These programs compute the canonical triplets for the given build, host, or target architecture. These programs are updated regularly to support new architectures and fix probes broken by changes in new kernel versions. You are encouraged to fetch the latest versions of these files from ftp://ftp.gnu.org/gnu/config before making a release.
locate config.guess ... /usr/share/doc/config.guess
# This script attempts to guess a canonical system name similar to # config.sub. If it succeeds, it prints the system name on stdout, and # exits with 0. Otherwise, it exits with 1. # # The plan is that this can be called by configure scripts if you # don't specify an explicit build system type.
