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

* 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. From-SVN: r76437
