/* This function is internal (it has a GLIBC_PRIVATE) version, but it
is widely used (either via weak symbol, or dlsym) to obtain the
__static_tls_size value. This value is then used to adjust the
value of the stack size attribute, so that applications receive the
full requested stack size, not diminished by the TCB and static TLS
allocation on the stack. Once the TCB is separately allocated,
this function should be removed or renamed (if it is still
necessary at that point). */
