Invalid configuration `x86_64-pc-linux-gnu’: machine `x86_64-pc’ not recognized

Нашёл в интернете, не смог определить первоисточник, поэтому копипаст.

Problem:

## ./configure
checking host system type… Invalid configuration `x86_64-pc-linux-gnuoldld’: machine `x86_64-pc’ not recognized
configure: warning: apparently your OS is not officially supported yet
configure: warning: this may not work
you’ll have to edit the makefile by hand

Solution:
edit file config.sub, add “x86_64-*” here:

# Decode aliases for certain CPU-COMPANY combinations.
case $basic_machine in

# Recognize the basic CPU types with company name.
