collect-ld.exe removed during bootstrap of a mingw compiler

[Nicolas Roche <roche at adacore dot com>]

Hi,

I am making attempts to compile GCC 4.1.1 for mingw and I got the 
following issue.

Before launching the bootstrap I am copying ld.exe to gcc/collect-ld.exe

The issue is that between stage1 and stage2 collect-ld.exe is removed 
and replaced by a shell script called collect-ld that calls 
./collect-ld.exe. So I get a bootstrap failure.

The issue is in gcc/Makefile.in. I have a patch (for the head and gcc 
4.1 branch) to fix that.

Thanks in advance for your review

Here is the Changelog and the patch

* Makefile.in (stamp-collect-ld): Fix issue when ORIGINAL_LD_FOR_TARGET 
is in . and that $(exeext) is not equal to ""
* Makefile.in (stamp-as): Idem for as
* Makefile.in (stamp-nm): Idem for nm
