misc/cgo/testcarchive: use -no-pie where needed

Starting in gcc 6, -pie is passed to the linker by default
on some platforms, including ppc64le. If the objects
being linked are not built for -pie then in some cases the
executable could be in error. To avoid that problem, -no-pie
should be used with gcc to override the default -pie option
and generate a correct executable that can be run without error.

Fixes #22126
