Norman Feske 4f820cf1e5 prepare_ports: prevent execution of automake
This patch discharges the dependency of Makefile.in from Makefile.am
files whenever both files are present in a downloaded archive.

Being based on make, the trigger of running automake is based on the
timestamps for the extracted archive content. However, since we reset
the timestamps (via 'tar -m') at extraction time, no assumptions about
the timestamp relations between the extracted files can be made. In the
event automake is triggered, we are faced with the tool dependency from
a specific automake version on the host.

The patch enforces the unconditional use the 'Makefile.in' version
supplied by the archive.

Fixes #4350
