Since its inception in9646e80fca(micropython: new package), the ppc-specific CFLAGS are simply assigned, and since9fd9f4e675(package/micropython: define MICROPY_NLR_SETJMP for xtensa), the same goes for the xtensa CFLAGS. Although they are mutually exclusive (different archs) and that there is no prior assignment, the customs are to use append assignment in conditional blocks, to avoid accidentally overwriting a valure set previously.
