TLS does not imply NTPL. TLS concerns handling of a new kind of 
relocation and it should be provided by the dynamic linker, while NPTL 
is the Posix implementation on a pthread library rather then using 
linuxthreads implementation.
Said that, I don't think addign TLS support for i386 is difficult, but 
we need someone having time to spend on it.

do you need TLS support or NPTL pthread library too?
