Compile benchmark programs without assertions

[Bruno Haible]

It is useful to disable debug assertions when benchmarking.
But not for the entire tests/ directory, of course — we want to know about
assertion failures in the unit tests.

This patch is not perfect, but good enough for the mb*iterf benchmarks.

        Compile benchmark programs without assertions.
        * modules/mbiter-bench-tests (Makefile.am): Compile bench-mbiter with
        -DNDEBUG.
        * modules/mbiterf-bench-tests (Makefile.am): Compile bench-mbiterf with
        -DNDEBUG.
        * modules/mbuiter-bench-tests (Makefile.am): Compile bench-mbuiter with
        -DNDEBUG.
        * modules/mbuiterf-bench-tests (Makefile.am): Compile bench-mbuiterf
        with -DNDEBUG.
        * modules/mbswidth-bench-tests (Makefile.am): Compile bench-mbswidth
        with -DNDEBUG.
        * modules/crypto/md5-buffer-tests (Makefile.am): Compile bench-md5 with
        -DNDEBUG.
        * modules/crypto/sha1-buffer-tests (Makefile.am): Compile bench-sha1
        with -DNDEBUG.
        * modules/crypto/sha256-buffer-tests (Makefile.am): Compile bench-sha224
        and bench-sha256 with -DNDEBUG.
        * modules/crypto/sha512-buffer-tests (Makefile.am): Compile bench-sha384
        and bench-sha512 with -DNDEBUG.
