The cgo tool determines whether testc is a function based in part on
the debug info generated by the C compiler. It looks like you are
using GCC; what version of GCC are you using?
You can make some progress in debugging this by running `go build -x`
to see exactly how cgo is invoked, then running that invocation and
adding the -debug-gcc option.
