[patch] Fix i386-mingw32 build failure

[FX Coudert <fxcoudert at gmail dot com>]

PING ** 2

Attached patch fixes PR bootstrap/22259 (right now, a simple ./configure 
&& make build fails on i386-mingw32). It creates a special case for 
in-tree as, collect-ld and nm scripts: since mingw32 cannot spawn shell 
scripts, it copies $(ORIGINAL_AS_FOR_TARGET), $(ORIGINAL_LD_FOR_TARGET) 
and $(ORIGINAL_NM_FOR_TARGET) in the tree.

There has been discussion on whether this is the best way to do things
(see thread from 
http://gcc.gnu.org/ml/gcc-patches/2005-07/msg01193.html), but nobody 
suggested another patch that actually makes build possible on 
i386-mingw32. And, from what I have understood, none of the mingw 
maintainers have anything against the patch, but they can't approve it.

Can someone with approval privilege over the build system look at this, 
and OK it? (it's a very simple patch)

Thanks,
FX
