Subject: [PATCH] [CMake] Look up target subcomponents in LLVM_AVAILABLE_LIBS
In an installation using the all-contained libLLVM.so, individual
components are not available as targets, so we have to look them up in
LLVM_AVAILABLE_LIBS just like llvm_map_components_to_libnames does it.
Here I don't think we need the capitalized names though because we know
the right capitalization. But I might be wrong.
This is required by dragonffi, who call llvm_map_components_to_libnames
on a list containing ${LLVM_NATIVE_ARCH}. Downstream bug report:
https://bugzilla.opensuse.org/show_bug.cgi?id=1180748.
