Subject: [PATCH 1/3] Support: hoist lld's executable name code to Path
Instead of using custom code to find the program name throughout
the codebase, write one function as a path helper to consistently
determine the program name. This globally correctly finds target
names with dots in them (ie freebsd13.2).
