[cdt-patch] new method: IBinary.isLittleEndian()

["Alain Magloire" <alain@xxxxxxx>]

2002-10-25 Alain Magloire

	The debugger needs to know the endian of a binary.  For example
	int the memory view, to do format.

	* model/.../model/IBinary (isLittleEndian): New method
	returns the endian.
	* model/.../internal/core/model/Binary.java (isLittleEndian): New method.
	* model/.../internal/core/model/BinaryInfo.java (isLittleEndian): New
	method implemented by calling Elf.
	* utils/.../utils/elf/Elf.java (Elf.Attribute.isLittleEndian): New
	method return the endian.
