I checked that with a profiled lto build. The build succeeds with the attached
patch to respect the parallel linking limitations, which you can configure with
--enable-link-serialization=N
However the build fails in the installation step with:

x86_64-linux-gnu-g++-10 is the compiler used for the bootstrap. I haven't
checked if that is also seen for a normal bootstrap. Apparently it tries to
re-bootstrap the compiler.
The build is configured with --with-build-config=bootstrap-lto-lean, built with
make profiledbootstrap-lean
