I can reproduce that failure with those CFLAGS. It looks like the build system always builds libvpx with SSE4 support. There is some code which should choose the appropriate instruction set at run time. I think you will need to remove -mno-sse4.1 from your CFLAGS.
I changed the cflags to -march=native and it works. but i cant use distcc to make a cross compilation. i will change the status to fixed thanks to gentoo team :)
(In reply to mercuriete from comment #3) > I changed the cflags to -march=native and it works. > but i cant use distcc to make a cross compilation. For distcc, you could probably just remove all of the -mno-XXX flags; most of them would not be enabled by default anyway.
