Log Message:
-----------
I have just proved CMake 2.8.11.2 can unpack *.xz archives using the

cmake -E tar zxf *.xz

command.  Therefore, drop using a system tar workaround for this
special case which reduces the differences between the epa_build
version of ExternalProject.cmake and the CMake version (which is
a good direction to go because eventually we may be able to
completely drop the epa_build variant of ExternalProject.cmake
