ladybird/Toolchain/Patches/llvm.patch
Andrew Kaster c5898806d2 Toolchain: Use Platform/SerenityOS.cmake in LLVM toolchain build 
By setting CMAKE_MODULE_PATH in the LLVM initial cache scripts, we can
make the "SerenityOS" CMAKE_SYSTEM_NAME usable in the builds of
compiler-rt, libunwind, libcxxabi and libcxx.

This simplifies some toolchain patches and brings the cross-compiler
patches closer to the Port's patches, and closer to something
upstreamable.
