xtensa ld fails with the following message ld: BFD (GNU Binutils) 2.31.1 internal error, aborting at elf32-xtensa.c:3283 in elf_xtensa_finish_dynamic_sections during domoticz package build. It happens because of mismatch between the size allocated for dynamic relocations in the executable image and the number of PLT relocations actually written to the image. The mismatch is caused by the fact that undefined weak symbol is treated as dynamic (and thus needing PLT relocation), but xtensa linker not expecting that.
