Add a simple test to the configure script to detect getline. It's not
important that the test run, just that it compiles and links without
any errors.

We were missing an "override" directive in the assignment of CFLAGS
within Makefile.config so it was actually having no effect. Then, we
were also failing to get the proper include path for valgrind.h so
it wouldn't have worked even it were having effect. Fix both problems.
We had avoided using "echo -n" originally for portability concerns,
and instead just printed the same string in both conditions, (and
also printed the string late if any check took long). The word is
that printf is quite portable, so we use that instead.
It was problematic to have this in "make install" since it would
unconditionally try to install to /etc, (even if a non-privileged user
was attempting an install to a prefix in the user's home directory,
for example).
I felt sorry for Carl trying to step through an exception from xapian
and suffering from the SIGALARMs..
We can detect if the user launched notmuch under a debugger by either
checking our cmdline for the presence of the gdb string or querying if
valgrind is controlling our process. For the latter we need to add a
compile time check for the valgrind development library, and so add the
initial support to build Makefile.config from configure.

This is *not* based on autoconf. In fact, this doesn't actually
configure anything, (one can compile notmuch directly with just
"make" without running configure if the dependencies are all
satisfied).
The only thing that this configure script does is to check for the
presence of the various dependencies and provide some guidance to
the user if they are not all available.
