[PATCH 2/3] [og9] Fix configury for AMD GCN testing

[Julian Brown]

This patch updates the configury for AMD GCN for version
of the patch "Forward -foffload=[...] from the driver (compile-time)
to libgomp (run-time)" currently applied to the og9 branch. This is
necessary for OpenACC testing on AMD GCN to work properly, at least in
our test environment.
