Details

The libvpx encoder uses (effectively) a $(CC) -S | grep to find symbols for its asm files to compile. When using clang lto, $(CC) -S produces an LLVM IR file instead of an x86 assembly file, causing the compile to break.

So, the simplest solution is probably to disable lto when building those files. We had to do a similar thing for MSVC (see bug 771588). Do you want to try to put together a patch for that?

This particular feature was removed from libvpx. I believe this is obsolete.
Long gone.
