Subject: [PATCH 08/54] Fix behavior when %_build_id_links is undefined

Commit bbfe1f86b2e4b5c0bd499d9f3dd9de9c9c20fff2 tries to behave sanely

and use compat setting when %_build_id_links is undefined, but

rpmExpand() never returns NULL so the original check is incorrect.

Check for empty string instead.

(cherry picked from commit 2ea72daabe3f0c4bef628d5a16768f293ffab3df)
