[Buildroot] [PATCH v1, next] package/llvm-project/compiler-rt: fix build with Ninja

[Thomas Devoogdt]

ninja: error: dependency cycle: include/sanitizer/allocator_interface.h -> include/sanitizer/allocator_interface.h

It's not clear why this cycle happens, but compiler-rt also proposes to
create a separate build folder on their site: https://compiler-rt.llvm.org/.
