Well.  The status is that only gold supports static archives
at the moment (and thus is able to LTO libbackend.a).  Also
WHOPR is largely disfunctional ATM.  The goal is to replace
the -combine mode with LTOing the host binaries at least
(eventually even installing static target libs with LTO bytecode
included so you can inline from libgfortran for example).

It's been some time since I last tried bootstrapping with LTO
enabled though ...
