The lto people need to engineer a design in which the debug information is left
around in .o files, and those files are read at the very last step in a link,
to collect the debug information from them and persist that information into
the filesystem.  They are removing .o files before the end of the final link. 
To the extent those files have debug information in them, this can't work.

I could not find the last invocation of gcc that fails.  If someone could point
that out, I might be able to suggest a work around that just disappears debug
information until such time as the first bug is fixed.  Essentially, you can
remove -g* from that line and disappear the collection of the debug
information.  Another solution would be to not have any .c, .cc, .C, .cpp, .cp,
.c++, .cxx, .CPP, .m, .mm, .f, or .s files on that line.
