LOWER_OS_VERSION not set on Linux

["Jeremy C. Reed" <reed%reedmedia.net@localhost>]

Running "print-PLIST" target causes every character to be delimited like:

...
${LOWER_OS_VERSION}s${LOWER_OS_VERSION}s${LOWER_OS_VERSION}l${LOWER_OS_VERSION}/${LOWER_OS_VERSION}b${LOWER_OS_VERSION}n${LOWER_OS_VERSION}.${LOWER_OS_VERSION}h${LOWER_OS_VERSION}
 
...

reed@puget:~/pkgsrc/wip/openssl$ bmake show-var VARNAME=LOWER_OS_VERSION

reed@puget:~/pkgsrc/wip/openssl$ bmake show-var 
VARNAME=_LOWER_OS_VERSION_CMD
echo 2.6.23.8 | tr 'A-Z' 'a-z'
reed@puget:~/pkgsrc/wip/openssl$ bmake show-var VARNAME=OS_VERSION
2.6.23.8


So I saw a typo for Linux where LOWER_OS_VERSION_CMD should have been 
_LOWER_OS_VERSION_CMD.

But I fixed that and resulted in:

reed@puget:~/pkgsrc/wip/openssl$ bmake show-var VARNAME=LOWER_OS_VERSION
echo 2.6.23.8 | tr 'A 'a

Notice the above does not have a trailing single quote.


Which broke other things.

What range is really needed here:

LOWER_OS_VERSION:=     ${_LOWER_OS_VERSION_CMD:C/-.*$//}
