Ok. So the following snippet:

+ ifeq ($(subdir),nptl)  [*]
+   libpthread-sysdep_routines += futex-helpers

Is not needed as it is already placed in /npt/Makefile. Am I correct?

So, only this modified (without ifeq above [*]) CFLAGS for
futex-helper.c compilation is needed?

When I put futex_abstimed_wait_cancelable64() as static __always_inline
to futex-internals.h then the aforementioned problem on m68k emerge.
