This question is perfectly relevant to this newsgroup.

The bad news is that you don't build an application explicitely against
LinuxThreads or NPTL. You build it against libpthread.so.0. Depending
on which system the program runs (or depending on the setting of
LD_ASSUME_KERNEL) the libpthread.so.0 corresponds to the NPTL or
LinuxThreads implementation.
