Subject: scripts/mkits.sh: fix portability issue
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b8bf27e4cb2d4c6ff4c75274c0e1d1619eef7f10;p=openwrt%2Fstaging%2Fthess.git

scripts/mkits.sh: fix portability issue

BSD wc can output more whitespaces, which breaks the cut usage.
Replace the cut invocation with awk, which is more portable.
