This reverts commit ebf341dc.

We can't force a prefix at make install with DESTDIR
files are installed in $(DESTDIR)/$(prefix) not $(DESTDIR)

This also breaks OSX binaries, and thus test suite (is that libtool's fault?)

VirtualFromSegments can crash if the std::vector passed in is empty, which
can happen in corrupted files. This is just a simple check for this case,
making it fail elegantly rather than crashing

High Quality DeNoise 3D, a port of the MPlayer filter, removes high-frequency

I must be missing something here... oh well.

don't run aclocal for those (we only patch Makefile.am)

- remove stuff we don't need
- replace prefix by template (.pc/.la/-config)
- include script to replace prefix template by $PWD
- use widely available bzip2 format so xz is not needed

Use:
$ make package-win32
$ make package-win64
$ make package-osx
$ make package-whatever
