+Subject: [PATCH 07/40] upstream change to garbage collection sweep causes mb
+ regression
+
+Upstream change for PR13177 now clears the def_regular during gc_sweep of a
+section. (All other archs in binutils/bfd/elf32-*.c received an update
+to a warning about unresolvable relocations - this warning is not present
+in binutils/bfd/elf32-microblaze.c, but this warning check would not
+prevent the error being seen)
+
+The visible issue with this change is when running a c++ application
+in Petalinux which links libstdc++.so for exception handling it segfaults
+on execution.
+
+This does not occur if static linking libstdc++.a, so its during the
+relocations for a shared lib with garbage collection this occurs
