Subject: [PATCH] Build system: sort object file lists

The object file list generated by the wildcard Makefile function is not
deterministic, because it may change depending on the underlying file
system.

Use the sort function to make the list deterministic in these cases, to
be able to build open-iscsi deterministically. See
<https://reproducible-builds.org/>
for further details.
