Unfortunately the people remaining are just as lost as me. No one has
attempted to build with dtrace so I'm in uncharted territory.

A diff of the object file doesn't give any useful information, the custom
version has a lot of differences since there have been a number of changes
from stock. postgresql_transaction__commit_semaphore does exist in the
symbol table of both .o files though when compared with objdump.
