Did ld.bfd ever work with those options?

I was told that both 2.22 and 2.25 also fail. It doesn't look like a regression.
With emacs 26.1, gcc (8.2.1 or 7.4.1) and most recent linkers, this does not seem to be anymore the case. In particular, the stripped binaries produced by ld.bfd ane smaller: With gcc 7.4.1 20181222 and linkers 2.31.51.20190103: 39536744bytes build-bfd/src/emacs 5394936bytes build-bfd/src/temacs 39545000bytes build-gold/src/emacs 5403192bytes build-gold/src/temacs With gcc 8.2.1 20190101 and linkers 2.31.51.20190103: 40253520bytes build-bfd/src/emacs 6100896bytes build-bfd/src/temacs 40265872bytes build-gold/src/emacs 6113248bytes build-gold/src/temacs
