bug#5927: `xz' command not found when running 'make dist and distcheck'

[jeff.liu]

Hello,

I run into a problem when running `make dist/distcheck' on "uBuntu 8.0.4 - the 
Hardy Heron".

The error message shows the `xz` command not found:
...
tardir=coreutils-8.4.84-8c4b6-dirty && /bin/bash
/home/jeff/opensource_dev/coreutils/build-aux/missing --run tar chof - 
"$tardir" | xz -c
>coreutils-8.4.84-8c4b6-dirty.tar.xz
/bin/bash: xz: command not found
WARNING: I can't seem to be able to run `tar' with the given arguments.
         You may want to install GNU tar or Free paxutils, or check the
         command line arguments.
make: *** [dist] Error 127


Is it make sense to add the pre-checking for `xz-utils' in 'boottrap.conf' like 
below?
