Using absolute paths for build tools is not how autoconf/automake 
expects to work. In particular, all of the built-in program checks in 
autoconf and automake expect build tools in the path (this is even 
mentioned a few times in the documentation). So if you need to use 
non-system tools, you ought to set the PATH accordingly.

So yeah, build bots shouldn't rely on configure doing it.
