no, if there's native windows tar it tries to use bzip2 which doesn't
exist, and the test fails. that's why it never failed before... it never
found tar before.
so rather, I think in this case we do have to check for bzip2 (we don't
now). it's less likely to be missing on Linux, but a quick experiment
shows if I manually get rid of bzip2, tar fails the same way:
# tar -tjf glibc-2.9.tar.bz2
tar (child): bzip2: Cannot exec: No such file or directory
tar (child): Error is not recoverable: exiting now
tar: Child returned status 2
tar: Error is not recoverable: exiting now

would a check for bzip2 look like this?
bz2 = test.Environment().WhereIs('bzip2')
looks like "figure out which tar" is not needed, just figure out if
bzip2 is there.
