Subject: r18452: add configure test for a getdirentries() based replacement
 for broken readdir()

Tru64 need this, linux also has getdirentries() but the native readdir() works
but it means we can write the code on linux and when it works it may work on Tru64
too.

tridge: can you try to implement this?
