Workaround libstdcpp TLS error (#19010)
Workaround https://github.com/apache/airflow/issues/17546 issue with
/usr/lib/x86_64-linux-gnu/libstdc++.so.6: cannot allocate memory in
static TLS block.
We do not yet a more "correct" solution to the problem but in order to
avoid raising new issues by users of the prod image, we implement the
workaround now.
The side effect of this is slightly (in the range of 100s of
milliseconds) slower load for any binary started and a little memory
used for Heap allocated by initialization of libstdc++.
This overhead is not happening for binaries that already link
dynamically libstdc++.
