Hi!
While working on the “reproducible builds” effort [1], we have noticed
that dropbear could not be built reproducibly.
The attached patch sets the mtimes of all files which are modified
during the built to the date of the last changelog entry in order to
produce files with reproducible metadata.
Cheers,
akira
