dtrace -G requires the ability to modify the object files in-place before
linking.  This causes havoc if the objects are in .a archives (dtrace can't
read those) or if the objects need to be linked into multiple binaries.  It
also destroys the ability to do an incremental build, as dtrace -G can't be
run on the same object twice.

The whole process is really a hack.  The build actions done by dtrace
should be done by the compiler and linker instead.  Getting the linker to
support the process would go a long way, as then dtrace -G could be run on
individual objects and most of my complaints go away.
