>Description:
Every time I run build.sh script, it prints an error in awk script and 
continues. I don't know whether it affects anything but this annoying message 
can be easily fixed.

See also bin/42320.

>How-To-Repeat:
$ cd /usr/src
$ LANG=ru_RU.KOI8-R AWK=/usr/bin/awk ./build.sh

or

$ LANG=ru_RU.KOI8-R AWK=/usr/bin/awk sh ./sys/conf/osrelease.sh -m
awk: syntax error at source line 1
 context is
        {print >>>  int($1+$2/100+0.01 <<< 
awk: illegal statement at source line 1

>Fix:
There are three different ways to fix this problem:

1. fix bin/42320
