The problem is that at the collect2 time we want to decide whether to
hold stderr/stdout of the linker. The issue is that we do not know yet
if we are going to LTO (because that is decided by linker plugin) or
whether we do repo files (because we look for those only after linker
failure).
We can look for repo files first but that could take some time
especially for large programs (probably not too bad compared to actual
linking later) or we may require -frepo to be passed to collect2.
