Hi,
when I compress (xz) folder with just one small file

/mnt/card #tar -cJv -f /akpkg.tar.xz akpkg/*
akpkg/sys.conf

and then try to decompress, I get this error

/mnt/card # tar -t -f /akpkg.tar.xz
tar: no gzip/bzip2/xz magic
/mnt/card # tar -tJ -f /akpkg.tar.xz
tar: corrupted data
tar: short read

With gzip or pure tar it works fine.
Compressed on PC (tar (GNU tar) 1.27.1)
and decompressed on busybox works too.

/mnt/card # busybox
BusyBox v1.22.1 (2014-04-14 14:39:49 CEST) multi-call binary.
/mnt/card # uname -a
Linux vyroba 3.17.4_cpm9g25 #6 PREEMPT Thu Nov 27 11:06:21 CET 2014 armv5tejl
