cmd/cgo/internal/test: test PPC64 ELFv2 call/plt stub generation
Verify functional stubs are inserted between TOC and NOTOC functions.
The implementation of the stub varies depending on -buildmode and
GOPPC64. Today, the type of stub generated by the internal linker
is roughly determined by the following
{GOPPC64 < 10, GOPPC64 >= 10} x {-buildmode=pie, -buildmode=default}
