build: sort objects to remove duplicates for link

Avoid duplicate object files during the link.  There are legitimate
cases where a link command-line would include duplicate object files
because two independent subsystems both depend on common infrastructure.

Use GNU make's $(sort) function to remove duplicate object files from
the link command-line.
