move alignment check from aligned_alloc to posix_memalign
C11 has no requirement that the alignment be a multiple of sizeof(void*), and in fact seems to require any "valid alignment supported by the implementation" to work. since the alignment of char is 1 and thus a valid alignment, an alignment argument of 1 should be accepted.
