Description
Neither gcc or clang support "-march=generic". But since https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/abc346de735cae1b9316b7b853aa2d2661ab40fb it can be used by the configure script.
Since the LTO linker flag is checked together with $cpuflags (https://git.ffmpeg.org/gitweb/ffmpeg.git/blob/e758b24396a427598ebb13e1589f6aeccdae0466:/configure#l7511), this results in the LTO linker flag not being used when linking the shared libraries which, in some cases, results in a build error.
