I looked through the options of LVM2 and compared them with the PKGBUILD
from ABS.  It would appear as though the default is to not enable
thin-provisioning, and the PKGBUILD does not have any inclusion of that
option either.  

/tmp/makepkg/src/LVM2.2.02.98 $ ./configure --help
...
--with-thin=TYPE        thin provisioning support: internal/shared/none
                          [[TYPE=none]]
...

It appears as though you need to edit the PKGBUILD and build yourself.
