[Buildroot] [FYI] jemalloc and valgrind

[Charles Hardin]

So, we hit an oddity on a “debug” build which turned out to be that if we have
valgrind installed - jemalloc would race and if it got build before valgrind then
it would not detect it.

I’ll try to make this a format patch later - but this is off another tree and so simple
that if someone wants to add it - I would suggest you do.
