[patch] toplevel configure.in: some skipdirs->noconfigdirs

[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.

It's 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 (powerpc*-*-winnt*): Ditto.
	* configure.in (powerpc*-*-pe*): Ditto.
	* configure.in (ppc*-*-pe): Ditto.
