erasure_code: use internal gf_vect_mul_base for ppc64le encoding

Browse Source 
gf_vect_mul_base is expected to work for all buffer sizes.
However, this function is checking for size alignment to 32 bytes,
to follow the other gf_vect_mul implementations.
Therefore, another implementation for this function is included
inside ppc64le folder to be used by the encoding functions.
