The issue with ffmpeg is a little more nasty though: it uses
__attribute__((aligned())) to align stack variables to 16-byte
boundaries for SSE. However, gcc2 does not support aligning variables
on the stack. Alignment of the stack itself is not sufficient for what
ffmpeg wants, so in gcc2 we'll keep having broken ffmpeg SSE code.
