A continuation of previous fix for malloc hooks which got removed from the new glibc library. The pre-compiled jemalloc has definitions which interpose hooks in glibc leading to linking errors with multiple hook definitions. A simple fix is to skip doing the workaround when using jemalloc from pre-compiled libraries. This will likely be revisited in the future, but for now it is important to fix compilation errors for developers.
