wrong. It's a matter of having TLS support in the uclibc.
uclibc trunk simply doesn't have it, nothing to do with NPTL.
Instead, nptl-branch (that requires TLS) has tls implemented for some archs.
At any rate, x86 has not it neither in NPTL branch.

FYI, __tls_get_address is a function automatically called by the compiler
when code needs to access a TLS variable (declared with __thread keyword)
by uing the dynamic access model.
