Failing build for NetBSD-amd64

[Adam <adam%netbsd.org@localhost>]

I can't cross-build NetBSD-current/amd64 on macOS anymore. I guess this is because of the new binutils. The build fails with this message:


dependall ===> lib/libc

I can remove LDFLAGS+=-Wl,--fatal-warnings from share/mk/bsd.sys.mk, then the build proceeds, but later fails with:

Am I doing something wrong?

I have HAVE_LLVM=yes defined.

I have successfully built for arm64 from the same source.

Kind regards,
Adam
