Bug#793754: libass: FTBFS on x32 because it tries to use amd64-specific asm

[Thorsten Glaser]

Source: libass
Version: 0.12.3-1
Severity: important
Justification: fails to build from source (but built successfully in the past)

Recent versions of libass install yasm on [any-amd64], which is an
architecture wildcard that does include x32 (because it matches on
the CPU architecture, not the Debian architecture, which surprised
me initially too).

The attached patch fixes libass by expanding the wildcard to those
desired [amd64 kfreebsd-amd64] and - just to be sure - adds an ex-
plicit Build-Conflicts on yasm [x32] (passing --disable-asm to the
configure invocation would probably also work).

Please apply!
