[FFmpeg-devel] [PATCH] Makefile: avoid cp-ing over existing executable files

[rcombs]

On macOS, code-signing information for executables (including those signed
automatically by the linker) is cached by the system on a per-inode basis.
The cp(1) tool will truncate and overwrite an existing file if present,
so we need to delete it first to avoid strange crashes.
