click e75d16b813 Core/Dependencies: Adjust jemalloc library caching methods - this will fix the startup-crash on linux-based systems.
Note: This is a temporary measure untill we've figured out why this occurs, further testing will be done.

* #include'ing jemalloc.h in order to cause name mangling that corresponds to
