Clear compile-time jemalloc definition about dwarfs HOT 4 CLOSED

In Gentoo there are USE flags, that are able to switch various configure-time and compile-time things. USE flags are used to for flexibility: you may build system your own

Hi @RarogCmex!

Nice, happy to hear that, I'm using Gentoo as my main distribution for more than 15 years. :)

With regards to libjemalloc-dev, that's a requirement I pulled in via folly. However, dwarfs only uses a small subset of the folly library, and it's entirely possible that this dependency is unnecessary. I'm not consciously using jemalloc anywhere, so it's quite possible that it's not needed. I've just checked and I've actually done all my testing on a Gentoo box that doesn't have jemalloc installed, so I'm pretty certain it's not needed.

The Lua support currently requires luabind, which I think is no longer in portage as it's basically unsupported. I've got my own ebuild for it, but long term I'd rather drop the dependency. So for now it's probably best to not add a USE flag for Lua support.

I've also just confirmed on a Ubuntu VM that the jemalloc dependency isn't needed.

@mhx Thank you for answer, I'll remove that dependency.
