Would it be possible to make it version-dependent, then?

As in, if GNU assembler is greater or equal to the version that
supports @FILE, then pass @FILE to it, otherwise fall back to
the current behavior.

I assume most people nowadays would have a version of
Binutils later than 2005, but if we could make it conditional on
the version then even those with earlier version wouldn't break,
they would just get the current behavior.
