Hello Emacs developers,

I am trying to native compile Emacs with the -flto flag patched into the
native-comp-compiler-options variable. However, when I do this, I get
the following error:

Hello all,

I'm closing this as I think this is not an Emacs bug.  Happy to re-open
if we discover it is :)

Thanks
