disable-yasm disables compiling of yasm files 
disable-asm disables asm code in *.c files

2. Yes, you will loose lot of performance. Try to install yasm on your embedded system, I'm sure it should be possible somehow if it's linux.

I realized that I also added --disable-asm option, which I thought that they are the same. Now I see that the libav compiles ./configure --disable-yasm.
