I think the standard version of linux on the omega2 is LEDE
The lzma loader src is:
https://github.com/lede-project/source/tree/master/target/linux/generic/image/lzma-loader/src
https://github.com/lede-project/source/blob/master/target/linux/generic/image/lzma-loader/src/LzmaDecode.c
Which is using LZMA SDK 4.22
