commit 7e423d6573b4a54834fffa97be0aedc28fe4aab8
Author: Leonard Lausen <lau...@amazon.com>

USE_JEMALLOC=OFF by default
As of jemalloc 5, jemalloc default build can not be used in libraries that
are dlopened. However, libmxnet.so is dlopened by Python (ctypes). To use MXNet
with jemalloc 5, users must not to system libjemalloc.so but must rather link
to a libjemalloc compiled with special parameters to allow dlopen to work.
jemalloc 5 is distributed as part of Ubuntu 18.10 and higher, as well as
Debian Stable. Users on these systems will be unable to compile MXNet with
USE_JEMALLOC=ON.
