Sanity checks added, local settings now in LOCAL.mk.in

The choice of whether or not to make a PDF is now also a local system
issue, not a general pipeline issue. So it has been put in the new
`LOCAL.mk.in' file which replaces the old `DIRECTORIES.mk.in'. All local
settings (things that when changed should not be version-controlled) should
be defined in this file.

A sanity check was added to find if `./configure' has been run before
`make' or not (using the `LOCAL.mk' file which is an output of the
configuration step). If `LOCAL.mk' doesn't exist, an error will be printed
informing the user that `./configure' needs to be run first.

The configure script also provides more clear and hopefully better
information on its purpose and what must be done.

Since `make clean', it is executed even when `./configure' hasn't been run,
it will only delete the build directory and its contents when local
configuration has been done.

A `distclean' target was also added which will first "clean" the pipeline,
then delete the `LOCAL.mk.in' file.

To allow rules like `make' to be run even if `BDIR' isn't defined
(`./configure' hasn't been run yet), a fake `BDIR' is defined in such
cases.
