Installer cannot use tar to extract from the suite archive

[CR #593410] You see this error on Sun Solaris when the installer uses the GNU tar tool to extract files from the suite archive:

The included VM could not be unarchived (TAR). Please
try to download the installer again and make sure that
you download using 'binary' mode.  Please do not attempt
to install this currently downloaded copy.

Workaround: Define /usr/bin/tar in $PATH.
