Subject: PR 5270 * main.cxx: Restored pre-10-08 version: moved uprobes build
 to buildrun.cxx. * buildrun.cxx: Reworked uprobes build so that the resulting
 Module.symvers can be used in building the stap-generated module.  If user
 isn't root, call verify_uprobes_uptodate() rather than trying (and failing)
 to rebuild uprobes.ko. * buildrun.h: uprobes_enabled() and make_uprobes() are
 no longer extern. * runtime/uprobes/Makefile: Added uprobes.ko target for use
 by verify_uprobes_uptodate().
