My CPU is Intel Core i7-4800MQ, but I realized my report was misleading.
I get that same error with
LDFLAGS=-flto
CXXFLAGS=-flto
CFLAGS=-flto
which results in

errors using binutils 2.25
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66029
--- Comment #6 from JD ---
Concerning the latest release of binutils, I have to admit I've never used a
local installation, so I might be doing something wrong here.
I downloaded and compiled version 2.25 and with that I get undefined references

--- Comment #9 from JD ---
I reconfigured and recompiled binutils 2.25 with the --enable-plugins and
--enable-lto flags.
But I'm afraid I must be missing something: Linking with the newly compiled ld
2.25 works fine without lto but using it with

Removing the -O3 flag from the first two invocations changes the behavior:
