Specifying the System Type

There may be some features configure can not figure out automatically, but need to determine by the type of host Bash will run on. Usually configure can figure that out, but if it prints a message saying it can not guess the host type, give it the --host=TYPE option. ‘TYPE’ can either be a short name for the system type, such as ‘sun4’, or a canonical name with three fields: ‘CPU-COMPANY-SYSTEM’ (e.g., ‘i386-unknown-freebsd4.2’).

See the file support/config.sub for the possible values of each field.
