As far as I know we haven't used this in a while, we don't build with it regularly, and in fact the Makefile with the commands to build with it has been deleted since right around the fbcode transition. It turned out to be the only thing holding LeakDetectable in the codebase, as well as a runtime option. We should just use jemalloc's profiling now if we need heap profiling, and maybe a bit of valgrind too. Differential Revision: D910760
