Log:
  [sh] Fix a "may be unused" warning on mips-gcc
  
  mips-gcc for mips32 was complaining that c was potentially used before
  being set.  Setting it to 0 before calling fdgetsc() looks like the right
  thing to do in this instance; there's an explicit check for c == 0 later
  on.
  
  Tested: mips-gcc mips32 build, running /bin/sh on mips32
