The new OPTIONAL_STATIC_TLS variable provides a means for applications
to increases the size of the static TLS space allocated by rtld beyond
the default of '128'.
The value specified in the variable must be no less than the default
value and no greater than the maximum allowed value for size_t type.
If an invalid value is specified, rtld will display an error message
and exit.
The rtld(1) man page is updated to document this new option.
