+Subject: [PATCH 2/5] Compile agsint llvm 3.2
 
 Current mclinker needs LLVM -r 173175 which contains re-org of
 some headers from since LLVM 3.2.  This patch is to roll back
 so we can build from LLVM 3.2

+Subject: [PATCH 4/5] Fix --build-id to not accept next arg
+
+Only the following two forms are allowed
+  --build-id             # default to sha1
+  --build-id=style       # choose style
+
+Neither swallow next arg, which happen to be "-m" when ld.mcld is invoked
+from clang, and cause GNU linker emulation fail

+Subject: [PATCH 5/5] Fixed darwin ld.mcld GNU -m emulation fail
+
+GNU -m emulation doesn't provide OS.  If ld.mcld is built on darwin
+the OS is incorrectly set to darwin.  Force to "linux" for Android.
