From bef4efb18c54f4b2285557a1b5a5a037f3dce019 Mon Sep 17 00:00:00 2001

Subject: scandir,readdir[_t]: use one common source for X() and X64()

Since the sources differ only minimally, use only scandir.c,readdir[_t].c
and redefine the used functions accordingly.
Use a strong_alias instead of compiling *64.c if __WORDSIZE = 64
