[Bug ld/10865] New: The entry point is mainCRTStartup

[giecrilj at stegny dot 2a dot pl]

The documentation of ld [1] says that the default ENTRY point is start.  This 
is not universally true; the default ENTRY point in MinGW is mainCRTStartup.

Steps to reproduce:

gcc -nostartfiles the following source code without crt2.o:

#include <stdio.h>
#include <stdlib.h>
int begin() { puts ("begin"); return 0; }
int start() { puts ("start"); return 0; }
int mainCRTStartup() { puts ("CRT"); return 0; }

The program prints "CRT", not "start".

In order to solve the problem, modify the documentation to say that the 
initial symbol is implementation-dependent.
