At the moment riscv64 toolchain can't be used to build
barebox for riscv32, e.g.
barebox$ make erizo_generic_defconfig
...
barebox$ make
...
riscv64-zephyr-elf-ld:
common/memory.o: ABI is incompatible with that of the selected
emulation:
target emulation `elf32-littleriscv' does not match `elf64-littleriscv'
The patch fixes the problem by explicit riscv32 target options selection.
