Why do you think this is an Emacs problem?  The error messages seem to
imply the problem is with your installation of libgccjit or
GCC/Binutils in general.  The request to submit a bug report cites a
Gentoo bug address, so I think you should report it there first.

Paul, does Emacs even support -flto builds?
