Previously, the SEH version of _Unwind_Backtrace did unwind
the stack and call the provided callback function as intended,
but there was little the caller could do within the callback to
actually get any info about that particular level in the unwind.
Set the ra and cfa pointers, which are used by _Unwind_GetIP
and _Unwind_GetCFA, to allow using these functions from the
callacb to inspect the state at each stack frame.

* unwind-seh.c (_Unwind_Backtrace): Set the ra and cfa pointers
before calling the callback.
Currently it is not possible to build GCC's libjava support on Cygwin-64.
This patch fixes the current build-problems on Cygwin-64 and the most
fundamental bugs on that platform.
Note you must still add --enable-threads=posix to successfully build the
java language support.
