[FFmpeg-devel] [PATCH v2] configure: Do not abort when cross-compiling to the native CPU
Using a compiler with a different host triplet is considered cross-compiling, even when it is for the same architecture as the build system. With such a cross-compiler, it is still valid to optimize builds with --cpu=host. Make the condition that aborts in this case into a warning instead, since a cross-compiler for an incompatible architecture will fail with -mtune=native anyway.
