RFA: x86 backend: Add default-manifest to Cygwin/MinGW links

No.  Well not in my opinion. :-)  The reason is that this patch only 
makes a difference if the default manifest can be found in a library 
search path.  If there is none present then nothing happens.  So you can 
disable the (broken) merging of a default manifest file by simply not 
having it present.  Which should be the case for all current installations.

Plus - I am hoping to fix the resource merging problem soon.  (Any day 
now, honest).  So I would like to have the gcc patch in place for when 
that happens.

Cheers
