[llvmlinux] Generating linux kernel .bc files

[Kai Wang]

When I do : cd targets/vexpress/ && make, the kernel can be successfully
compiled by clang.
HOSTCC = llvmlinux/toolchain/clang/head/install/bin/clang
CC = llvmlinux/toolchain/clang/head/install/bin/clang

But when I do : cd targets/vexpress/ && make BITCODE=1, there are errors.
HOSTCC = llvmlinux/toolchain/clang/head/install/bin/clang
CC = llvmlinux/arch/all/bin/clang-emit-bc.sh

I guess there is some problem with "clang-emit-bc.sh". Any suggestions?

Thank you.
