The error mean that the process tries to load a dso (shared library) that
was build with initial-exec TLS model, and there is not enough space in
the initial TLS segment reserved by rtld to accomodate the dso needs.

As a temporary measure, you might try to play with the LD_STATIC_TLS_EXTRA
env variable to specify the desired size.  Default value is 128 bytes.

For gcc and clang, the TLS model is controlled by -ftls-model switch.
No idea how to pass this through rustc.

One possible reason why you get the initial-exec model is when dso code
was compiled in non-pic mode.
