gitian: add statically built variant of bitcoind/bitcoin-cli
Show error message if ReadConfigFile fails

A runaway exception was raised if ReadConfigFile fails (usually
due to a parse error in bitcoin.conf). Show an error message instead.

Fixes #4013.
build: Sync ax_boost_base.m4 with upstream.

This should fix 32bit boost detection on Ubuntu Saucy+. Fixes #3945.
