[Bug lto/42776] New: LTO doesn't work on non-ELF platforms.


As per title, and see also the discussion in bug 41529.

There is no fundamental requirement for ELF to be the object format, as the
object file sections are just used as dumb containers for arbitrary binary
data.  The interface between lto-elf.c and the rest of lto1 needs only the
ability to create sections and to place and retrieve binary data in/from them,
so should be easy to implement for any object format that allows
arbitrarily-named sections; that's everything except a.out I would suppose.

I'm only planning to fix this for the PE-COFF (windows) platforms, but I'll try
and make the code general enough so that it works on other COFF platforms and
just needs enabling by the relevant target maintainer.
