Surprisingly, it actually did:

$ time make package PKG_SUFX=.tbz
===>  Building package for llvm40-4.0.0_2
565.215u 5.316s 9:34.18 99.3%   7899+502k 1+3020io 0pf+0w
                ^^^^^^^
Single-threaded bzip2 was faster than multi-threaded xz, at the expense
of larger package of course:

$ ls -s1 llvm40-4.0.0_2.t*
386752 llvm40-4.0.0_2.tbz
286816 llvm40-4.0.0_2.txz

Or, like vsevolod@ had mentioned, Zstandard.  But I'm afraid it would
take some time before we'd arrive there.
