Subject: [PATCH] explicit_map_components_to_libraries now does not complain
when there is a dependence on an LLVM target that is not included on the
build.
When LLVM_TARGETS_TO_BUILD didn't include all the targets, the
function emitted an error like
"Library LLVMArmParser not found in list of llvm libraries."
