[PATCH] build: Fix undefined 'LIBTOOL' error.

[Collin Funk]

Hi,

When building from the main branch I see the following error:

guile-readline/Makefile.am:47: error: Libtool library used but 'LIBTOOL' is 
undefined
guile-readline/Makefile.am:47:   The usual way to define 'LIBTOOL' is to add 
'LT_INIT'
guile-readline/Makefile.am:47:   to 'configure.ac' and run 'aclocal' and 
'autoconf' again.
guile-readline/Makefile.am:47:   If 'LT_INIT' is in 'configure.ac', make sure
guile-readline/Makefile.am:47:   its definition is in aclocal's search path.

Then autogen.sh fails. This is because libtoolize is not called. The
version is announced so I assume the intent was to actually call it.
I've attached a patch doing so.

Then I see the following warning:

automake: warning: possible forward-incompatibility.
automake: At least one source file is in a subdirectory, but the 
'subdir-objects'
automake: automake option hasn't been enabled.  For now, the corresponding 
output
automake: object file(s) will be placed in the top-level directory.  However, 
this
automake: behavior may change in a future Automake major version, with object
automake: files being placed in the same subdirectory as the corresponding 
sources.
automake: You are advised to start using 'subdir-objects' option throughout your
automake: project, to avoid future incompatibilities.

This option has been around for a long time. I have just added it to
AM_INIT_AUTOMAKE to silence the warning.
