[libstdc++] Cleanup build system 9/n

[Kelley Cook]

This removes PACKAGE and VERSION from acconfig.h and replaces them with 
AH_TEMPLATES.

As PACKAGE and VERSION don't seem to be actually used (except in make 
dist which we don't do), either removing the Automake "no-defines" 
option or just deleting them would probably also work, but this is 
clearly the safest method as it leaves all the generated files the same 
except for whitespace and comments.

It also updates the configure.ac How to reconfigure comment :)

OK?
