Change how endianness is reported

Don't put variables in all project's config.h but only generate a .endian
file when skalibs is a dependency, i.e. for limb.
limb will then generate an endian.h header with proper macros.

Probably a better/more generic solution (for all sysdeps?) would be nice;
This will do for now.
