    contrib/gcc-12: Add local -save-temp=objects option
    
    The upstream has considerably reworked how the -save-temps option (and
    friends) works [1], so we have to adjust the GCC-8 patch [2] for GCC-12.
    
    Meanwhile, apply commit d0443a708c [3] to the gcc.1 man page.
    
    [1] revamp dump and aux output names
