Title: Support 64-bit builds and restarting build process

Two changes to support 64-bit builds, based on detecting machine
hardware name as 'x86_64':
- change gmp build flags from "ABI=32" to
"--enable-cxx --build=x86_64-linux"
- link a 'lib64' folder to 'lib' to fix a problem with libnettle
and libhogweed not being found for 64-bit builds of 'gnutls'

Three changes to allow the build process to be restarted if a failure
occurs while building:
- Supply a workaround for a known bug in pkg-config 0.28, which has
been fixed upstream to remove a file created during the build
- Supply "git pull" alternative to "git clone" where the target
folder already exists
