    editors/libreoffice: make robust against __cxa_exception ABI changes

    Patch libreoffice 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 libreoffice
    to detect this so packages built on 13.0 still work on 13.1.

    Change the LIB_DEPENDS on libunwind to a BUILD_DEPENDS because we only
    need unwind.h (for FreeBSD 13.0 and older where that header is hidden
    in /usr/include/c++/v1).
