Thanks, indeed.  If we came into "#elif WORDSIZE == 32" block, above

"#if...#elif...#elif...#endif" block.  Here is a revised patch.

------------------------------------------------------
From: Atsushi Nemoto <anemo@mba.ocn.ne.jp>
Subject: [PATCH] getdents: Fix mips64 build

Some archs (such as mips64) do not have getdents64 syscall but have
getdents syscall.  Define alias for it.

This fixes regression from 0.9.30.1.

Backgrounds:
This is once done by commit e8b1c674.  But after the commit 33bcf733
("Use getdents syscall if kernel provide supports for this instead of
relying upon getdents64."), if __ASSUME_GETDENTS32_D_TYPE was defined
the alias for getdents64 is not defined.  The macro
__ASSUME_GETDENTS32_D_TYPE had been effectively ignored until 0.9.30.1
but the commit 0f0f20ab ("Move kernel-features.h header from the
linuxthread directory to a common one...") really enables it.
