>Description:
Hi!

I'm doing mass builds right now (Toolchain, NetBSD, Linux kernel, ...) and found an issue with the Open Firmware support. Host GCC is Debian's "gcc-snapshot":

/usr/lib/gcc-snapshot/bin/gcc --version
gcc (Debian 20210508-1) 12.0.0 20210508 (experimental) [master revision 292da5c58da:d8763feb89a:62d87a321b29f9febdacc6220367021d98db3057]

Build is done as:

./build.sh -P -U -m macppc -a powerpc64 tools
./build.sh -P -U -u -m macppc -a powerpc64 release
