Mapper contains binary file format implementations which are known to
break on Big Endian machines. Mapper remains usable without these file
formats since the current native format is based on XML. However, the
loss of the OCD format would harm exchange with common proprietary
software. This might surprise some users.
In addition, I didn't see a possibility to do Big Endian builds without
much effort. This is now mitigated by the possibility to build with
openSUSE Build service (even locally) for s390x. However, all changes
which I could implement upstream would arrive in 0.7.x or later, and
cannot easily be backported, due to major changes in source file
structure and in CMake files.
