commit 44b6c77c64d367eb3c9227cf1c0fbaff4ab294b2

    Try fixing linking again
    
    Before 1.7.5, we were setting -fno-exceptions etc on CXXFLAGS. In 1.7.6
    we set it as CPPFLAGS. Try fixing. Also, I'm fairly sure it's safe to
    set these unconditionally.
    
    Fixes https://github.com/harfbuzz/harfbuzz/issues/880 (or so I hope)
