mc: Fix build reproducibility

Fixes some issues with reproducible builds. Adds a patch to allow the
configure arguments to be omitted from the build and also explicitly
setting some autoconf paths that were picking up hosttools.

+Subject: [PATCH] Add option to control configure args
+
+Embedding the configure time options into the executable can lead to
+non-reproducible builds, since configure options often have embedded
+paths. Add a configure time option to control if the configure args are
+embedded so this can be disabled.
+
