[Already approved by Janne Blomqvist and Jeff Law.  Included here for
completeness.]

This patch contains the GCN port of libgfortran.  We use the minimal
configuration created for NVPTX.  That's all that's required, besides the
target-independent bug fixes posted already.

	libgfortran/
	* configure.ac: Use minimal mode for amdgcn.
	* configure: Regenerate.
