This patch adds a default manifest in to the final links performed by the Cygwin and MinGW targets.
The manifest is necessary in order for the linked binaries to be executed in a Windows 8 environment.
The manifest is added using a linker script so that this feature will be compiler-neutral. The resource
merging code in the linker means that if an application provides its own manifest then the default
manifest will be ignored.

by invoking configure.tgt.
