[FFmpeg-devel] [PATCH] configure: Add dash before arflags

[avener]

From: averne <averne381 at gmail.com>

This allows specifying additional flags with 
`./configure --ar='ar -<...>`.
Previously this resulted in commands such as `ar rcD -T`,
which give an error ("no operation specified"), on certain
versions of ar (eg 2.30-ubuntu).
