I've finally put two and two together and identified the cause,
--fix-cortex-a53-835769, which was kicking in for -mcpu=cortex-a53. Looks like
an LTO gold linker bug, period.

FWIW, an LTO bootstrapped gcc is actually slower, taking 2 more minutes to
complete a --disable-bootstrap build (3% slowdown).
