[PATCH] coverity: i386: build.c: negative return to unsigned fix
Variable "c" was declared as an unsigned int, but used in:
125 for (i=0 ; (c=read(fd, buf, sizeof(buf)))>0 ; i+=c )
126 if (write(1, buf, c) != c)
127 die("Write call failed");
(akpm: read() can return -1. If it does, we fill the disk up with garbage).
