Subject: [PATCH] gnu: jemalloc: --disable-initial-exec-tls

Disable the thread local storage model in jemalloc 5 to prevent
shared libraries linked to libjemalloc from crashing on dlopen().
https://github.com/jemalloc/jemalloc/issues/937

This bug affects both Java JNI and python libraries which link to
jemalloc 5, such as RocksDB, which will crash the program when loaded.

* gnu/packages/jemalloc.scm (jemalloc)[arguments]: Add --disable-initial-exec-tls
configure flag.
