As of 4.9.2, gcc started passing -fno-lto to collect2, or to ld if collect2 cannot be found. The latter is the case for our bundles, because we don't include collect2. Unfortunately, ld does not understand this option and errors out.
On the bright side, -fno-use-linker-plugin still works to suppress gcc's LTO, so we can drop -fno-lto.
