-mno-unaligned-access is ARM32 only, unfortunately. You'd have to
convince GCC developers to generalize it.

The problem is that the CBFS stage and payload headers themselves
contain inherently misaligned 64-bit values. I guess if the compiler
was really smart it could stack-allocate a struct { u32 a; u64 b; }
__attribute__((packed)) structure at an odd 4-byte boundary, but it
doesn't currently seem to do that (and neither does cbfstool for the
in-ROM structs).
