This is a known issue. There is currently no way to tell buildroot that an
external toolchain is using NPTL.

There has been a discussion about in in the recent past, but I can't recall
what was the outcome...

Basically, buildroot should not have to know what threading implementation
is being used, as it has no partical user-visible impact. There are currently
only two packages that have dependency on NPTL: openvpn and ltp. For others,
you should be able to safely use an NPTL toolchain without telling buildroot.

I'll look into that during the WE, hopefully.
