In my own build of jemalloc, I see via nm(1) that in libjemalloc[_pic].a and
jemalloc.o, the __*_hook symbols are read-only data ('R'), but they should be
writable ('D'), as they are in libjemalloc.so.1. This problem arises because
jemalloc mistakenly declares the hooks as const, so they are indeed read-only
(whoops). Here's the fix:

Thanks,
