[MPlayer-dev-eng] mvi on alpha ev56 (i.e. there isn't any)

[Andrew A. Gill]

I'm having some trouble with compiling MPlayer-1.0-pre1 on a DEC Alpha
ev56.

I'm compiling it with GCC-3.2.2, and I keep getting complaints about
assembly operands.  Trouble is, it looks like it's trying to build support
for MVI, but Alpha ev56 doesn't support MVI.

This might be a libavcodec problem, but as far as I can tell, the relevant
code in that makefile is unchanged.

So I propose a patch (attached).  Note that I don't program shell scripts,
so this might not even work, but the concept should be sound.
