I have fix for the linking issue (attached). However, a bootstrap in the deep
profiling grade now gets a SIGSEGV when making the stage 3 dependencies,
even when if I undo the commit that fixed Mantis bug 514 (commit c5b35aca...),
which was the previous change that directly affected deep profiling.
So this needs further investigation.
