#
#
Configuration subroutine to validate and canonicalize a configuration type.
#
Supply the specified configuration type as an argument.
#
If it is invalid, we print an error message on stderr and exit with code 1.
#
Otherwise, we print the canonical config type on stdout and succeed.
#
You can get the latest version of this script from:
#
https://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub
#
This file is supposed to be the same for all GNU packages
#
and recognize all the CPU types, system types and aliases
#
that are meaningful with *any* GNU software.
#
Each package is responsible for reporting which valid configurations
#
it does not support. The user should be able to distinguish
#
a failure to support a valid configuration from a meaningless
#
configuration.
#
The goal of this file is to map all the various variations of a given
#
machine specification into a single specification in the form:
#
CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
#
or in some cases, the newer four-part form:
#
CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
#
It is wrong to echo any other type of specification.
