linux64.h (MD_FALLBACK_FRAME_STATE_FOR): Corrected to handle kernels with changed ucontext.

Browse source 
* config/rs6000/linux64.h (MD_FALLBACK_FRAME_STATE_FOR)
	[!__powerpc64__]: Corrected to handle kernels with changed ucontext.

	* include/powerpc-signal.h: Add #ifndef __powerpc64__ around the
	header.  For __powerpc64__ provide the default-signal.h definitions
	for now.
	* include/x86_64-signal.h [!__x86_64__]: Include java-signal-aux.h
	instead of the dummy definitions.
	* configure.host (x86_64-*): Remove CHECKREFSPEC, add DIVIDESPEC.
	(powerpc64*-*): Remove with_libffi_default.
	Only add -mminimal-toc for 64-bit compilations.
	* configure.in: Use powerpc-signal.h on powerpc64 as well.
	(x86_64-*-linux*): Set SIGNAL_HANDLER_AUX.
	Link SIGNAL_HANDLER_AUX to include/java-signal-aux.h.
	* configure: Rebuilt.
