{-*.so,.so.*,.so*} should also work, I will change to that.

{*.so,.so.*} will add more files:
$ ls -al lib/libc{*.so,.so.*}
lib/libc.so
lib/libcc1.so -> libcc1.so.0.0.0

A little bit offtopic.
With LEDE 17.01 branch this is sufficient to use a external musl 
toolchain, on the master branch the Linux kernel will not build because 
it has some problems with the includes, it looks like it gets more 
includes than the kernel wants. When I modify the wrapper file manually 
and remove all the extra gcc options the kernel and all the other stuff 
compiles fine.
