If I don't use --disable-altivec I get

        Assembler messages:
        Error: invalid switch -m7400

much earlier.

I guess the point here is I'm using GNU assembler 2.9.5 (of Debian 2.2r6)
which doesn't understand -m7400 or opcodes like `vspltish'.  That's fine
for me because my CPU doesn't have these instructions.  I would only
like the xine build process to behave under these circumstances.
