Subject: [PATCH] configure: Make autoconf fail if libtool is not installed.
Otherwise users get an error later like:
./configure: line 5093: syntax error near unexpected token
`disable-shared' ./configure: line 5093: `LT_INIT(disable-shared)'
It's probably friendlier to make configuration fail earlier.
