    gcn/mkoffload.cc: Pass -save-temps on for the hsaco step
    
    For the assembly/linking step of the device code, the "-save-temps" was not
    passed on, such that amdgcn-amdhsa/bin/as and amdgcn-amdhsa's collect2
    were invoked with '-o /tmp/cc...' and '@/tmp/cc...', respectively.
    The -dump... prefix (...mkoffload.hsaco) was already properly set.
    
    gcc/ChangeLog:
    
            * config/gcn/mkoffload.cc (main): Pass -save-temps on for the
            hsaco assemble/link.
