True, but how many more copies of the same patterns do we want?  Add FreeBSD, OpenBSD, ... whenever they arrive?  Isn't the common pattern <linker> <object file> <flang rt libs> with or without `-lm`?  How about putting the first under one label and the `-lm` part under another, used where appropriate?
