Description: find endianness on every Debian architecture
src/Core/OOCPUInfo.h maintains a hand-made list of architectures of each
endianness. It uses environment variables when available, I guess this is
used when hardware supports both. This build process fails for unknown
architectures (alpha ia64 s390).
.
Some systems provide sys/param.h, and among them some define __BYTE_ORDER.
Upstream avoids this solution as-is since it fails on some of their systems.
