Based on the script which is producing this output, I updated all the
Makefile.am with right dependencies. This was needed since many deps
changed since the Makefile.am were wrote. Please note that I had to
comment some of them because of cyclic dependencies or because the
processing order is way too complicated to do.

Please note that I may have broken the trunk under Linux.

I also removed a borring "bug" (" because some people call it a feature)
describe here:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=419228


If you have 3 libtool convenient libs:
libA => libB => libC
libC will embded all the dep that libA has. 

In Scilab case, this was causing some stupid stuff like:
The boolean library had to do a string test, then we linked it to the
scilab String library which is using pcre. This was causing lib boolean
to link the pcre library.

For those who will find this email on Google (or me, in a few months
when I will have forgotten how I did it), I am using the Debian patched
version of libtool currently the one in unstable (1.5.26-1).
I updated the appropriate files doing 
# libtoolize -c -f 
And I use the macros:
AC_PROG_LIBTOOL 
AM_PROG_LIBTOOL 
in the configure.ac

And, still in the configure.ac, I added the option:
link_all_deplibs=no
to make sure that deps are not propagated.

And finally, watch you the version you are using, I found a few bugs in
it.
