Confirmed.  This issue is still present - even the LTO linker plugin identifies
files via that mechanism :/

Looks like simple things "stick" ...

libiberties simple-object could be used to instead query for a
.gnu.lto_.opts section.

The collect2 issue might eventually be "fixed" by making LTO require using
the linker-plugin path.
