Carl reports "gcc -aux-info notmuch.aux lib/notmuch.h" does not
generate notmuch.aux for him with Debian gcc 4.6.0-8.
Based on a suggestion by Austin Clements, this version uses objdump to
get the symbols from the object files.
Any symbol that
- is in some object file in $(libnotmuch_modules), and
- starts with notmuch_
will be exported.

Here is another way of doing this, probably better unless you are
very attached to the idea of declaring the API in the header file.
