+Subject: [PATCH 01/11] [Patch, microblaze]: Add config/microblaze.mt for
+ target_makefile_frag Mirror MIPS method of creating copy of default.mt which
+ drops the compilation of generic sbrk.c to instead continue using the
+ microblaze provided version.
+
+[Libgloss]
+
+Changelog
+
+2013-07-15  David Holsgrove <david.holsgrove@xilinx.com>
+
+  * config/microblaze.mt: New file.
+  * microblaze/configure.in: Switch default.mt to microblaze.mt.
+  * microblaze/configure: Likewise.
