This removes a dependency of checkasm on lavc/v210_enc.o and also allows to inline ff_v210enc_init() irrespectively of interposing. This dependency pulled basically all of libavcodec into checkasm, in particular all codecs. This also makes checkasm work when using shared Windows builds: On Windows, it needs to be known to the compiler whether a data symbol is external to the library/executable or not; hence the need for av_export_avutil. checkasm needs access to the internals of the libraries it tests and is therefore linked statically to all the libraries. This means that the users of avpriv_cga_font and avpriv_vga16_font in libavcodec (namely ansi.o, bintext.o, tmv.o) end up in the same executable as the symbols, although they have been compiled as if these symbols were external, leading to linker errors. With this commit said files are discarded by the linker, bypassing this problem. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
