[PATCH 2/2] test/libnotmuch-abi: compare exported symbols, available symbols, and linker script.

[david at tethera.net]

From: David Bremner <bremner at debian.org>

This uses objdump and awk to grab the available "notmuch_" symbols
from the object files and all exported symbols from libnotmuch.so. The
symbols from the linker script are grabbed using sed.  All three of
these sets of symbols should be equal.
