If bsdtar is installed, fix script error for tar version detection.
bsdtar does not provide all expected command line (long) options
like "--hard-dereference". To ensure compatibility, mark version
of tar as 'invalid' and trigger build of 'host-tar'.

Some toolchains, like the one built with buildroot itself, use hardlinks (for
example to link between the c++ and g++ binary). Unpacking such a toolchain
with the --strip-components options does not work correctly if the system tar
is too old (<1.17). Even recent releases of RedHat/CentOS still ship with
tar 1.15.
This patch checks for a suitable tar version (tar 1.17+) on the host system,
and adds host-tar to the host dependencies if none can be found.
host-tar is download and extracted as cpio.gz instead of tar.gz, to prevent
chicken-egg problem.
