> You enable LTO by default if a suitable libelf is found.  But what if

> an ELF target?  Presumably LTO will not work in that case (i.e., it
> requires the target to be an ELF target rather than producing ELF files
> separate from the normal objects for that target)?  So shouldn't LTO be
> disabled for non-ELF targets even when libelf is present?  We discussed a

> supported by GCC and (b) not ELF is better than trying to list all ELF
> targets.  Certainly various ELF targets are missing from the list used to
> set is_elf for --enable-gold.)
