how to regenerate automake files

[Paolo Bonzini]

I just found out that just running "automake" is not enough if you have 
installed Autoconf 2.59 as "autoconf-2.59", and a newer Autoconf as just 
"autoconf".

You have to do
   AUTOM4TE=autom4te-2.59 automake

(possibly something like "AUTOM4TE=autom4te-2.59 automake-1.9").

I thought that sharing this bit of wisdom would be appreciated.
