>Description:
As freebsd-used awk was changed from gawk to 'real' awk in 5.x, all the shell scripts that set awk variables in a style -vVAR=val will silently produce incorrect results.

>How-To-Repeat:
# echo azb | awk -Fz -vOFS=q '{print $1,$2}'
a b
# echo azb | awk -Fz -v OFS=q '{print $1,$2}'
aqb
# echo azb | gawk -Fz -vOFS=q '{print $1,$2}'
aqb

>Fix:
workaround:
1. install gawk
2. replace awk binary with gawk or put gawk into /usr/sbin as awk (/usr/sbin is normally before /usr/bin in $PATH).
