Endianess is not the only concern. We had a bug recently that looked
(I didn't look close) like GCC generated instructions that didn't care
about the LBSs in pointers (in C pointers are aligned, right?). So
best option we have are the read/write functions in `commonlib/endian.h`,
IMHO.

But I think that deserves a broader discussion.
