+    toolchain/gcc: .init and .fini need to pick one ISA
+    
+    The .init and .fini sections are built by concatenating code
+    fragments. Putting mips16 code in the middle of a mips32 code block
+    doesn't work. Make gcc built the magic crt stuff in no-mips16 mode.
+    
+    This is specific to 4.6-linaro but is probably portable to other gcc
+    flavors. Adding this to the t-libgcc-mips16 makefile fragment is a
+    hack not suitable for pushing upstream, but there is no mips/t-linux
+    or mips/t-uclibc and I am not going to touch gcc/configure for two
+    lines.
