config.guess: unable to guess system type、config.sub: missing argument

一个简单的错误： 

onfigure: error: cannot guess build type; you must specify one      

一个复杂的错误：

./configure
./config.guess: unable to guess system type
 
This script (version 2018-02-24), has failed to recognize the
operating system you are using. If your script is old, overwrite *all*
copies of config.guess and config.sub with the latest versions from:
 
  https://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.guess
and
  https://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub
 
If ./config.guess has already been updated, send the following data and any
information you think might be pertinent to [email protected] to
provide the necessary information to handle your system.
