I checked every /usr/bin/*.dll on my system (which is a lot), and these
three, plus cyglsa64.dll (which can only be read by
x86_64-w64-mingw32-objdump), are the only ones which show this.  I did
manage to reproduce this on my machine with openssl, and passing
--long-section-names=enable to objcopy does fix this, but why are only
these DLLs affected?
