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)
