little example: https://github.com/lesleyrs/builtin-fail
When there are 2 symbols available (builtin and import_name) it unexpectedly causes undefined symbol linking error.
There's no great workaround for this, because the existing builtins change per clang version, so if you decided to do specific `-fno-builtin-xxx` that could fail to compile on newer clang versions.
I think it's best for builtin to just override the import_name the same way that builtins override other funcs, especially since the builtin math funcs only appear when math.h is included. (I'm importing math funcs from JS)
