For testing we (ab)use the assembler to build us a sample dtb, independent of the other tools (dtc and libfdt) that we're trying to test. In a few places this uses 64-bit arithmetic to decompose 64-bit constants into the individual bytes in the blob. Unfortunately, it seems that some builds of GNU as don't support >32 bit arithmetic, though it's not entirely clear to me which do and which don't (Fedora i386 does support 64-bit, Debian arm32 doesn't). Anyway, to be safe, this avoids 64-bit arithmetic in assembler at the cost of some extra awkwardness because we have to define the values in 32-bit halves.
