The chosen payload compression algorithm can be changed by overriding
`OPKGBUILDCMD`. Ensure that package extraction deals with this by
globbing for "data.tar.*" to select the actual payload tarball.

What happens if we have two consecutive builds with the same build
directory but different compression algorithms? Would we have two
data.tar.* matches?
Each call to extract() creates a new temporary directory into which the
content of that particular IPK are extracted. IPKs should contain only
one data tarball and as such the described scenario should never occur
(and the length check I added is a merely a safety measure).
This makes sense, thanks for taking the time to explain.
Cheers,
Quentin
