#36 VOS: big/little endian auto detection does not work in any environment

[mike]

The big/little endianess setting of the individual target (implemented in vos_utils.c) does not work in any target environment:

The following list of defines needs to be evaluated as true by the preprocessor in order to get a big endian target to be correctly recognized:
BIG_ENDIAN || ARMEB || AARCH64EB || MIPSEB

The drawback is, that not all compilers define such macros.

An always clean solution would be, that the compiler settings per platform contain for instance a directive -DBIGENDIAN or -DLITTLEENDIAN

I will change config files in the config directory and change the detection implementation to force the definition of endianess by having a compile time error thrown

Put in solution outlined on page [Endianess] as [r1261]
