It looks like when transitioning to using target and optimization
option nodes for compile-time to link-time option streaming you
didn't adjust lto-opts.c nor lto-wrapper.c. The following fixes
the target option side (for SWITCHABLE_TARGET). Do not record
any target options in the lto_opts section.
Honza - I suppose we don't have any testcase that this works, I'll
try to come up with sth. This also looks like a correctness issue
to me.
We can do similar changes for optimize options, now, for all targets, no?
Thanks,
Richard.

* lto-opts.c (lto_write_options): Do not record target options
if we are targeting a SWITCHABLE_TARGET target. We use target
options on functions to transfer target flags from compile to
link time.
