Yet Another test option

[Bruce Korb]

Hi Chet, et al.,

Given that sort(1GNU) now has a sort-by-version-ordering (sort -V),
it would seem reasonable to do version comparisons without having
to do a series of fork & execs.  In other words, abbreviate this:

    min_os_ver=`
      printf '2.6.27\n%s\n' "$LINUXRELEASE" | sort -V | head -1`
    if test "X$min_os_ver" = "X2.6.27" ; then

into something like this:

    if test "2.6.27" -Vle "$LINUXRELEASE" ; then

or add a different operator to [[ ]] contexts?
