Compiled LLVM trunk in Release mode.

Downloaded LLVM-GCC from svn trunk.

Configured LLVM-GCC:

/work/temp/obj-arm$ ../llvm-gcc/configure --prefix=/work/temp/obj-arm/install
--program-prefix=llvm- --enable-llvm=/work/temp/llvm --enable-languages=c,c++
--target=arm-none-eabi

Ran "make", got error:
