misc/cgo/test/issue9400: fix to build with gccgo

This doesn't test much with gccgo, but at least it builds now, and the
test does, unsurprisingly, pass.  A proper test would require adding
assembly files in GCC syntax for all platforms that gccgo supports,
which would be infeasible.

Also added copyright headers to the asm files.
