toplevel configure.in tweak

[Nathanael Nerode <neroden@doctormoo.dyndns.org>]

For some reason these targets were adding things to skipdirs rather than
noconfigdirs.  The only practical difference is that the warning message 
"This configuration is not supported in the following subdirectories" 
would not show up.  (This has been tested.)

It's (significantly) simpler for me to clean up the newlib-related code if 
they use noconfigdirs the way every other target does.

So unless someone comes up with a good reason they should behave differently,
I suggest this patch.

	* configure.in (*-*-netbsd*): Use noconfigdirs, not skipdirs.
	* configure.in (sh*-*-pe*): Ditto.
	* configure.in (mips*-*-pe*): Ditto.
	* configure.in (*arm-wince-pe): Ditto.
