"build_alias" again in cygwin

[Smith, Gene]

I seem to be having basically the same problem that Steve Strobel had 
back in Jan 2002 with thread called ""build alias" trouble under cygwin".

It seems to be a random thing. He removed his virus checker and got it 
maybe working better. (Mine is locked in with a p/w which I don't have.) 
Also, changing the ./configure script parameters around sometimes made 
it better. In the end, no resolution was posted.

My /usr/bin/sh is definitely bash:

$ sh --version
GNU bash, version 2.05b.0(1)-release (i686-pc-cygwin)
Copyright (C) 2002 Free Software Foundation, Inc.

Sometimes ./configure will finish, sometimes not. Also, when it does, 
"make all" will fail with complaint about build_alias too.

I do see some "no" results on the ./configure before the build_alias 
failure (see below). The one that looks odd is "check if cross 
compiling... no."

$ ../rtems-4.6.1/configure --target=powerpc-rtems --disable-posix 
--disable-networking --disable-cxx --en
