`csp` can't be cross-compiled due to use of `_csptypesimpl` during the build #264

Because _csptypesimpl is used during the build, if it is cross-compiled to a different arch it won't be useable. So during the build we should either:

compile it for universal2 on Mac which will be useable everywhere, but won't work on linux since the equivalent doesn't really exist
compile it for native for the build, then cross compile it just for distribution
