Addition to config/gen/makefiles/root.in at r48140 causes multiple re-builds

[mikehh]

The changes to config/gen/makefiles/root.in in r48140 cause src/extra_nci_thunks.c to be re-generated every time the all target is make is invoked.

At the moment I have commented the lines out and assigned the ticket to darbelo who committed it based on a patch be cxreg

The file is re-generated in make test (after make which also regenerates it), and in make smoke, make fulltest and make install, for example.
