Some assembler optimised code cannot be made relocatable with a simple
compiler flag. Speaking of libdv, there's a C fallback that could be
built position independent, but the impact on performance is tremendous.
Given your proposal, I'd have to build a shared lib off the C version
and teach each dependent package not to use it, but the optimised static
version. Looks rather awkward to me.
