Chris Wilson 986f6c9824 notmuch-new: Only install SIGALRM if not running under gdb
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.
