PATCH Fix java/lang/ieeefp.h for arm-netbsdelf


ARM systems running NetBSD/ELF use a pure-endian floating-point system (as 
used by the VFP co-processor).  We can tell this by the presence of the 
pre-processor macro __VFP_FP__.  This patch adds support for this format 
in libjava.

	* java/lang/ieeefp.h: Handle ARM platforms that have pure-endian
	floating point.
