Re: 1.16.90 regression: configure now takes 7 seconds to start

At some point, it becomes unreasonable to burden common platforms with 
delays that only support relatively obscure and obsolete platforms.  
Configure scripts already have a bad reputation for wasting time.  Even 
if they are faster than editing a custom makefile, they are idle instead 
of active time for the user, so waiting is harder.

I feel that 6-second test delays or 2-second incremental delays later 
qualify as clearly unreasonable.  The 1-second timestamps are borderline 
unreasonable.  Cross-compiling with a decent filesystem is more 
reasonable.

Why can't we resolve this by requiring systems with 2-second resolution 
to set a flag in config.site?  That moves the burden closer to where it 
belongs.
