Subject: [PATCH 1/4] configure: support silent automake rules if possible

This gives us a much less noisy build and makes error stand out a lot more.

Subject: [PATCH 2/4] configure: acconfig.h is deprecated since autoconf-2.50

Remove deprecated file (leftover from autoconf-2.13). Change AC_DEFINE into
3-arg versions to provide the comments for config.h. Bump autoconf version to
2.59 (same as libxml).
