+Subject: [PATCH] estrip: Don't use splitdebug for .o files
+
+As the process_ar comment explained, object files cannot be splitdebug.

+Bug: https://bugs.gentoo.org/787623 ("www-client/firefox[clang]: .gnu_debuglink is busted when using LLD")
+Fixes: 51579fb34c19 ("prepstrip: add support for elfutils strip")
