bitbake rust-llvm -c do_configure is broken

[DeepeshvRajan]

bitbake rust-llvm -c do_configure is failing

git clone https://github.com/yoctoproject/poky
cd poky
git clone https://github.com/kraj/meta-clang
source oe-init-build-env
vi conf/bblayers.conf
add meta-clang layer
and bitbake rust-llvm -c do_configure

| x86_64-poky-linux-gcc: error: unrecognized command-line option '--rtlib=libgcc'
| x86_64-poky-linux-gcc: error: unrecognized command-line option '--unwindlib=libgcc'

| ninja: build stopped: subcommand failed.

I guess this is because of the following commit
521fcaf

Note : Without adding meta-clang layer the issue is not seen.

yes, you might have to test with #1116 until its merged. Its waiting for some commits from oe-core master-next to land in master. So for best results use master-next branch from poky with yoe/mut branch of meta-clang for brief period.
