Useful binaries for RTS3903N Linux 3.10

Linux version 3.10.27 (zhangzhidan@XY-201) (gcc version 4.8.5 20150209 (prerelease) (Realtek RSDK-4.8.5p1 Build 2521) ) #29 PREEMPT Wed May 22 14:16:12 CST 2019

Update: 10/10/2021

I've now compiled and included the uClibc 0.9.33 interpreter with LD_PRELOAD enabled (disabled by default on the stock SDK), this is incredibly useful for hooking/trampoling library calls.
Usage: mount -o bind ld-uClibc-0.9.33.so /lib/ld-uClibc-0.9.33.so

Here is a collection of binaries I've compiled while debugging and developing on the RTS3903N chipset.
