Add gfortran support for AMD GCN 

From: Kwok Cheung Yeung <kcy@codesourcery.com>

This patch adds enough support for constructors/destructors and OS functions
to be able to link and run gfortran programs on AMD GCN.

There's no actual ability to do I/O operations on this targets, besides
"write" to stdout and stderr, so most of the functions are just stubs.
