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.
