Commit Message

The CALL_PSELECT6 is now only defined in the sysdeps/unix/sysv/linux/pselect.c
file and was introduced to allow i386 specific assembler implementation
of pselec6 (with 6 arguments).

As the i386 now supports pselect6 syscall and the assembler implementation
(in the sysdeps/unix/sysv/linux/i386/call_pselect6.S) has already been
removed it is safe to remove this macro define.

Tested with:
- make PARALLELMFLAGS="-j8" && make xcheck PARALLELMFLAGS="-j8" (x86_64)
- scripts/build-many-glibcs.py

Typo: "pselec6"

I would just say that nothing defines CALL_PSELECT6 in the current tree.
That's enough reason to remove it.

Thanks,
