Regarding Libtool, sure.  However, we need to ascertain if and how the 
new sysroot functionality affects GCC (in particular if the configure 
options are incompatible).

Regarding Autoconf, I'd rather see a further upstream release before 
upgrading, and also waiting a month after the release.  I'm not 
comfortable with forcing GCC contributors to use a release with known 
regressions (though not affecting GCC).

On the other hand, given the above plan I would be okay with upgrading 
Autoconf during early stage 3.
