Description of problem: Jemalloc package is built without profiling support. If there is no technical reason for not including it, it would be really nice to be able to profile allocations. Also it's misleading that jemalloc-devel contains jeprof utility for profiler data analysis, but jemalloc itself can't produce such data. Additional info: Could be fixed by adding --enable-prof flag in configuration step of the build script.
