When creating programs with large text sections on ppc64le, trampolines are needed for calls that are too far; however they are not created if the code is generated such that the TOC register r2 is initialized and maintained in the code because then the external linker can create the trampolines. Previously the function DynlinkingGo was used to determine this but in the case where plugins are used, this could return true even though r2 is not valid. To fix this problem I've added a new function r2Valid which returns true when the build options indicate that the r2 is initialized and maintained. Because of the ways that DynlinkingGo is used I wanted to maintain its previous behavior.
