I see this, too.
BTW, some more info:
This looks similar to
https://github.com/systemd/systemd/issues/234
and was worked-around in systemd commit aac7c5ed8bc6
("build-sys: hide magic section variables from exported symbols")
until reverted in commit 780950a2ba58 ("Revert "build-sys: hide
magic section variables from exported symbols"") because binutils
was fixed since.
This error should only ever happen with old versions of ld.gold.
In addition, gold should be fixed by now:
https://sourceware.org/bugzilla/show_bug.cgi?id=18548
https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=5417c94d1a944d1a27f99240e5d62a6d7cd324f1
but something is amiss here.
ld -v gives
GNU ld (GNU Binutils) 2.30.0.20180208
so this is a bit strange...
Cheers,
Andre'
