commit 6b84eeb21628a89b40c985b527d3d5db7806c93c

    Move processing_gcc to stabsread
    
    processing_gcc is also only used by stabsread -- it is set by the
    DWARF reader, but this turns out not to be needed.  So, this patch
    moves processing_gcc and removes the assignment from the DWARF reader.
