Home-built using buildroot. I have three different xtensa toolchains
(de212, dc232b, and dc233c). The toolchain for kc705_nommu needs the
de212 overlay; I think Max pointed to to the information needed
to build the compiler. Buildroot has the "XTENSA_OVERLAY_FILE"
option to specify the compiler overlay file for the target.
