I believe so.


So, in order to get gcc14 to use binutils gas on NetBSD 10 I made the 
following change to the Makefile.common

--- Makefile.common     21 Apr 2025 20:26:50 -0000      1.8
+++ Makefile.common     16 Sep 2026 20:51:09 -0000

But with that change the make of gcc14 dies trying to build libgcc

Don't see why just changing the assembler would have the effect.
