[ptxdist] [PATCH] ptxd_make_get_git: use singlethreaded compression with XZ

[ptxdist] [PATCH] ptxd_make_get_git: use singlethreaded compression with XZ

[Lucas Stach]

XZ switched to use multithreaded compression by default in versions
after 5.4. Unfortunately this changes the checksum of the resulting
archive, as the compression algorithm isn't exactly the same when
multithreading is used.
