build: avoid stdin stall with GNU AS probing.
a758c5e added probing for various tools, such as AS. Unfortunately, GNU AS is reading stdin with -v, and thus configure is stalled with configure arguments such as --as=as. Fixes Ticket #1898. (cherry picked from commit dbb41f93c16cbc65a899a75723c95da51c851cd5)
