[FFmpeg-devel] [PATCH] configure: add -fno-semantic-interposition to optflags

[Anton Khirnov]

Gcc flag -fsemantic-interposition, which is on by default with current
gcc versions, makes the compiler assume exported symbols can be
interposed by the linker, which prevents various kinds of optimization.

Since we do not support such interposition and disable it with
-Bsymbolic, explicitly disable this assumption.
