[LEDE-DEV] [PATCH] musl: update to 1.1.17

[Syrone Wong]

Hi,

I tested commits between 39db00afadc9d8d0456c46eab42b8cb8ff9f375c and
c10bc61508dc52b8315084e628f36a6c3c2dabb1.

Finally, I find 8c4be3e is causing the problem. 565dbee is the last one working.


Commands below for every libc ipk.

```
make toolchain/musl/{clean,compile} V=99
make package/toolchain/{clean,compile} V=99
cp libc_*.ipk /tmp
tar zxf libc_*.ipk
tar zxf data.tar.gz
cd lib
mv ld-musl-armhf.so.1  libc.so /lib
reboot
```

Best Regards,
Syrone Wong
