This commit provides the appropriate external symbol addresses to let the "btree" example natmod build for the Xtensa platform. On the ESP8266, unsigned integer division code isn't provided as part of libgcc.a, libm.a, or libc.a, but it is instead provided by the ROM. Regular builds inject the appropriate symbol addresses as part of the linking process (see eagle.rom.addr.v6.ld), but natmods need this information brought in from somewhere else.
