Log:
  fdt: Expect strchr() to return a const char*
  
  In C, strchr(3) returns a char*, whereas C++ defines two overloads:
  * const char *strchr(const char*, int)
  * char *strchr(char*, int)
  
  Building fdt.cc (with the WITHOUT_GPL_DTC knob set) with libc++ 3.9.0 (imported
  in r309124) was failing because libc++ r260377 added the first overload to
  string.h, leading to failures such as:
  
      fdt.cc:1638:8: error: cannot initialize a variable of type 'char *' with an
      rvalue of type 'const char *'
  
  Just define val as a const char* to fix it.
