Agreed.

object file matching in check_format_matches goes like this: The default target
matches even when other targets do too. Next targets with highest priority
(lowest match_priority) match, which in this case would exclude generic ELF.
Of those with highest priority the first one matches. That ought to match
anything in the config targ_selvecs before targets added by --enable-targets.
However, something else must be going on with archive armaps.
I suspect why you don't see it now with --enable-targets is that the default
target for sparcv9-solaris2.11 has changed. If I configure with
--target=sparc64-sun-solaris2.11 --enable-targets="sparc64-elf,sparc-elf" an
archive with a 32-bit sparc object lacks the armap. Without --enable-targets
we get an armap. This happens with both normal and thin archives. I'll take a
look some time when I have a spare moment.
