[FFmpeg-devel] [PATCH] configure: Fix DEF file post-processing with LTO enabled.

[Kacper Michajłow]

With LTO enabled exported symbol entry looks like:
av_audio_convert @3 DATA

In order to maintain valid format we need to strip everything after @.

This patch fixes linking libraries compiled with MinGW toolchain with LTO enabled.
