commit 97b2a20b55acf76ebaacff0054e0f3c2b4236847
Author: Richard Purdie <richard.purdie at linuxfoundation.org>

    dpkg: Add PACKAGECONFIG for liblzma and enable it
    
    liblzma is part of xz and we already build it but configure it out. This makes
    no sense. Enabling it means we gain multithreaded compression and it speeds
    dpkg-deb up massively. It also removes the fork overhead of separate xz processes.
    
    Turning the existing config into a PACKAGECONFIG and turning it on by default
    therefore makes best use of what we have available.
    
    The manual RDEPENDS are no longer needed since it uses liblzma which is picked
    up by the shlibs code magically.
