build: Guard the inclusions of config.h with HAVE_CONFIG_H

autoconf can be configured to not generate a config.h but to give the
defines with command line arguments instead. In this case, there's no
config.h to include.

To work in both cases autoconf adds a HAVE_CONFIG_H define on the command
line to signal there's a config.h to include.
