I searched, and while bug number 28853 is close, I don't think its the same one. When I emerge mplayer I can see that its applying my optimizations, plus other ones, that don't apply to me. I have an athlon, but not an athlon-tbird, so why should -mcpu=athlon-bird be done? Also, I spotted -O4...which I thought was a 'fictional' 'O' setting, as they didn't get past three. I think packages like this break the spirit of Gentoo. I have no experience in doing this kind of thing, but perhaps something should be done to filter out some of these automatic CFLAGS...

No, the ebuild unset all CFLAGS, and compile it as mplayer wants, else they do not support it. If you have issues with this, edit the ebuild, or take it to mplayer-users - I should however warn that it is part of their support policy, and I cannot see it changing soon.
