Cross-building NetBSD on Solaris 11.4 has been working perfectly 
for quite some time.

I have daily CI builds running on the gcc buildfarm Solaris systems 
cfarm215 and cfarm216 (https://portal.cfarm.net/machines/list/)

Recently switching to gcc14 broke the build, but a simple hack solves the 
issue until I have time to come up with a proper solution.

The issue is that Solaris nm is not the same as gnu nm.
