[Bug bootstrap/39470] [melt] - lrand48_r() and srand48_r() are GNU extensions and are not portable

Workaround:

Define this at top of one file and export it in the other:

struct drand48_data
  {
    unsigned short int __x[3];  /* Current state.  */
    unsigned short int __old_x[3]; /* Old state.  */
    unsigned short int __c;     /* Additive const. in congruential formula.  */
    unsigned short int __init;  /* Flag for initializing.  */
    unsigned long long int __a; /* Factor in congruential formula.  */
  };


Use these versions of __drand48_iterate(), nrand48_r(), lrand48_r() and 
srand48_r() at the top of one of the files (with exports in the other):

http://cvs.sourceforge.jp/cgi-bin/viewcvs.cgi/uclinux-h8/uClibc/libc/stdlib/lrand48_r.c?view=markup&revision=1.1.1.1

http://cvs.sourceforge.jp/cgi-bin/viewcvs.cgi/uclinux-h8/uClibc/libc/stdlib/srand48_r.c?view=markup&revision=1.1.1.1

The build continues ...
