openwrt 无法运行 dig nslookup，问题“Error relocating... symbol not found”，求助

首先我觉得这是软件包或者依赖库的版本问题

$ sudo opkg update
$ sudo opkg install bind-dig bind-libs

最终执行 dig 相关命令时得到错误

Error relocating /usr/lib/libisc-9.18.0.so: uv_sleep: symbol not found

google 了一下失望了，在此求助该如何 debug ？

目前我所知道的：

# musl libc 的版本是 1.1.24
# ldd
musl libc (x86_64)
Version 1.1.24
Dynamic Program Loader
Usage: ldd [options] [--] pathname

问题依然无解。bind-libs 是以下程序的依赖项

bind-host
bind-nslookup
bind-dnssec
bind-rndc
bind-check
bind-dig

尝试更换过 bind-libs 的版本，还是不能正常运行 dig (运行 nslookup 也是一样的问题). 还看到一些说 libc 库版本问题的，这个库版本号不能通过 opkg 进行更新，只能刷写新的固件解决。

重装系统的代价有点大，有没有大佬指点下在不重装系统的情况下该怎么 debug 让 dig 、nslookup 等软件正常运行。
