Subject: [PATCH 3/3] configure.ac: no serial-tests if automake < 1.12

Earlier versions of automake complain if they get a configuration
parameter which they don't understand.  The error is:

configure.ac:27: error: option 'serial-tests' not recognized

Use some m4 hackery to work around this.

Fix libgcrypt build under x86_64
