busybox编译问题

[sdc_sh]

SPLIT include/autoconf.h -> include/config/*
GEN include/bbconfigopts.h
/bin/sh: line 1: /home/dcshen/file/busybox-1.7.0/scripts/mkconfigs:

Permission denied
make: *** [include/config/MARKER] Error 126
我在编译busybox时出现上面的问题，不知如何解决，有知道的朋友告诉一声

ls -l /bin/sh

如果没有就sh连接就
cd /bin
ln -sv bash sh

[sdc_sh]

我看了一下，它已经是到bash的链接了，还会是什么别的原因呢，请教
[dcshen@server dcshen]$ ls -l /bin/sh
lrwxrwxrwx 1 root root 4 Mar 7 2007 /bin/sh -> bash

[hefuhua]

vi /home/dcshen/file/busybox-1.7.0/scripts/mkconfigs
看看第一行是啥
