[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).
