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

Browse Source 
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?
