This reverts commit 396648cc.

The commit made impossible to build against libflite if libasound is not
available (e.g. on Windows). Thus remove the -lasound flag. In case of
libflite static linking the workaround is to enable
--extra-ldflags=-lasound (or disable the ALSA output device in libflite).

libflite depends on libasound. Fix a linking failure when linking against
a static version of libflite.

This is required due to the way VC-1 handles chroma pull-back which may end
up causing negative chroma MV for zero luma MV. Edge emulation needs to be
invoked in such cases.

This only affects vertical component of chroma motion vector.
