Make robust against __cxa_exception ABI changes
Patch OpenOffice to replace __cxa_get_globals()->caughtExceptions,
which is a pointer to the start of a struct __cxa_exception, with
__cxa_current_primary_exception(), which is a pointer to the end. This
allows struct __cxa_exception to be extended at the start as was
recently done in FreeBSD main and stable/13 on 64-bit architectures.
Recently on FreeBSD main and stable/13 __attribute__((__aligned__)) was
added to struct _Unwind_Exception which changes its size on 32-bit
architectures, and that of __cxa_exception as well. Patch openoffice
to detect this so packages built on 13.0 still work on 13.1.
