[PATCH] fix --with-cpu for sh targets

[Rich Felker]

A missing * in the pattern for sh targets prevents the --with-cpu
configure option from being accepted for certain targets (e.g. ones
with explicit endianness, like sh2eb).

The latest config.sub should also be pulled from upstream since it has
a fix for related issues.
