+- Update to 0.17.3:
+  * Fix 0.17.2 regression in the fontconfig fontprovider leading to

+  * Fix configure generated with slibtool-provided autoconf macros
+  * Fix make check for shared-only builds
+  * Constify some API parameters in a backwards-compatible manner
+  * Add new ass_malloc and ass_free API functions
+  * Tweak default optimization flags
+  * Speed up parsing of events with very long override blocks
+  * Improve handling of HarfBuzz-related failures
+- reintroduce 'make check' as the issue has been fixed upstream
