# Usage: config.sub CPU-VENDOR-OS
# config.sub ALIAS
#
# Validate and canonicalize the given configuration name, with special
# handling for GMP extra CPU names.
#
# When the CPU isn't special the whole name is simply passed straight
# through to configfsf.sub.
#
# When the CPU is a GMP extra, configfsf.sub is run on a similar CPU that it
# will recognise. For example "athlon-pc-freebsd3.5" is validated using
# "i386-pc-freebsd3.5".
#
# Any canonicalizations made by configfsf.sub are preserved. For example
# given "athlon-linux", configfsf.sub is called with "i386-linux" and will
# give back "i386-pc-linux-gnu". "athlon" is then reinstated, so we print
# "athlon-pc-linux-gnu".
# Expect to find configfsf.sub in the same directory as this config.sub
