Subject: [PATCH] lavu: fix compilation with Apple's llvm-gcc

Change DECLARE_ASM_CONST macro not to use the static qualifier,
preventing a linking failure when using the declared costant from a
function's scope.

In practice, this fixes the compilation of software like mplayer that
fails to link vf_fspp.
