With your recent removal of SDB and -gcoff support, I would appreciate
your advice about my patch to incrementally add some preliminary LTO
support for AIX to collect2.c:

There don't seem to be any other COFF targets around that still use
the collect2 code to manually scan object and archive files. And I
don't think that they would be hurt by the additional search for the
LTO symbol. I want to check if anyone is aware of a potential problem
before I commit the code.
The patch is OK.
cygwin uses collect2, but it is using the generic support, not the COFF
specific support.
The generic support has a check for to verify that we have an object
file and not an archive file. See maybe_lto_object_file. You might
want to add equivalent code to the COFF support.
