On PPC64 when external linking, for large binaries we split the text section to multiple sections, so the external linking may insert trampolines between sections. These trampolines are within the address range covered by the func table, but not known by Go. This causes runtime.findfunc to return a wrong function if the given PC is from such trampolines. In this CL, we generate a marker between text sections where there could potentially be a hole in the func table. At run time, we skip the hole if we see such a marker. Fixes #37216.
