Title: Fix build with automake >= 1.12

According to the ```NEWS``` in 1.12:

- The warnings in the category 'extra-portability' are now enabled by
'-Wall'. In previous versions, one has to use '-Wextra-portability'
to enable them.

Fixes this error message when running ```autogen.sh```:

automake: warnings are treated as errors
/usr/share/automake-1.12/am/ltlibrary.am: warning: 'libsubmarine.la': linking libtool libraries using a non-POSIX
/usr/share/automake-1.12/am/ltlibrary.am: archiver requires 'AM_PROG_AR' in 'configure.ac'
lib/Makefile.am:1: while processing Libtool library 'libsubmarine.la'
lib/Makefile.am: installing 'build-aux/depcomp'
autoreconf: automake failed with exit status: 1
