poudriere testport log on 12.0-CURRENT without the patch

On recent 12.0-CURRENT, japanese/mh has failed to build.
It has been occurred with a creation failure of config/version.c.
config/version.c is created with the config/version.sh script.

The version.sh script changes its IFS (Input Field Separators) variable
in the middle of the script from the default value (space, tab, and newline)
to ":".

After some command execution, it restore the IFS variable from ":" to " "
(not the default value).  It should be restored to the default value
for usual operation.  But the script doesn't do it, and has caused
odd behavior with recent 12.0-CURRENT (after r317559?).

To solve the problem, restore the IFS variable to the default value
appropriately.

* Simplified test script (from config/version.sh)

$ OFS="$IFS" IFS=:
$ LOCAL=`hostname`
$ IFS=" "                               # Should be 'IFS="$OFS"'
$ echo ' ('$LOCAL') of '`date`'";'

** Result on 12.0-CURRENT (r318250) - Bad.
