  Addressed the review comments, the tricky static TLS accounting
bits are unchanged. These are still outstanding:

> Subsequent followup after committing this:
> - We need to fix tst-manyaudit.
> - We should be able to count how many spaces we need based on LD_AUDIT
>   or DT_AUDIT and enable up to that amount.

Reran the tests on aarch64 and x86.

Szabolcs Nagy (2):
  rtld: Add rtld.nns tunable for the number of supported namespaces
  rtld: Avoid using up static TLS surplus for optimizations [BZ #25051]
