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 dbb41f93c1)
The function requires increasing the fuzz factor for the ac3/eac3 encode
tests and even so makes fate fail. It only provides a slight encoding
speedup for legacy CPUs that do not support SSE2. Thus its benefit is not
worth the trouble it creates and fixing it would be a waste of time.
This ensures that frames do not get mixed on context reinits
