+Subject: [PATCH] Fix xtensa ld segfault when linking linux modules
+
+is_inconsistent_linkonce_section makes an assumption that section name
+that starts with ".gnu.linkonce.prop." has one more dot in its suffix.
+However gas generates such section name by insertion of "prop." right
+after ".gnu.linkonce." part of the name of the original section. So, for
+section named ".gnu.linkonce.this_module" corresponding property section
+name does not satisfy the assumption. Such section names are common in
+linux modules. This bug was exposed by the patch "a35d5e8 Fix alignment
+for the first section frag on xtensa", that makes gas produce property
+section for each section that has ".align" directive in it.
+
+Use suffix that immediately follows ".gnu.linkonce.prop." when there are
+no more dots following it.
