Searching around, I found other distros hit the same problem for their POWER ports, and needed to explicitly configure GCC >= 6.2 to build with 128-bit floating point types. Specifically, with the option '--with-long-double-128': https://github.com/advancetoolchain/advance-toolchain/commit/e22696eecb39c6b401df14001f01608807e4d934 http://lists.busybox.net/pipermail/buildroot/2017-August/200952.html I hope that helps!
