    ARC: Adjustments for gcc 4.8 · 5a45da02
    Vineet Gupta authored
    * DWARF unwinder related
      + Force DWARF2 compliant .debug_frame (gcc 4.8 defaults to DWARF4
        which kernel unwinder can't grok).
      + Discard the additional .eh_frame generated
      + Discard the dwarf4 debug info generated by -gdwarf-2 for normal
        no debug case
    
    * 4.8 already uses arc600 multilibs for -mno-mpy
    
    * switch to using uclibc compiler (to get -mmedium-calls and -mno-sdata)
      and also since buildroot can only use 1 toolchain
