>Description:
On investigating the build failure for macppc port in the HEAD-LLVM branch, I managed to build a release successfully from FreeBSD 11.1.

ofwboot.xcf on the CD is non bootable an explodes shortly after producing the first line of test with the version / date the build happened. This issue was previously reported by jmmv on the port-macppc
list
https://mail-index.netbsd.org/port-macppc/2017/12/03/msg002464.html

Turns out the kernels built in this release work just fine.
I copied the netbsd-install.gz kernel to disk & booted the system from that instead. I was able to perform an upgrade of an existing install partially without issue. All the sets I'd built extracted just fine but the final steps such as the sysupgrade process failed to run.
Reboot the system, the kernel boot up just fine but as the system went to go multi-user, the init process crashed with 
trap: pid 1.1 (init): user read DSI trap @ 0x10 by 0xfde171c8 (DSISR 0x40000000, err=14)
and continued to fill the screen with the same message over & over again.

>How-To-Repeat:
./build.sh -U -m macppc -V MKLLVM=yes -V HAVE_LLVM=yes -V MKGCC=no release
and install on a PowerPC Mac

 This is also tracked as port-macppc/44895 which contains more info

 Reverted and brought sources up to date before starting a fresh build.
 GENERIC kernel wont boot.

 Before I tested the new build, I poked around & found that on the
 INSTALL kernel with the minimal tools on memory disk, things worked
 (binaries did not crash upon execution) so I mounted the hard disk which
 NetBSD was installed on and tried to execute the binaries there. The
 standard utilities which are dynamically linked would not work but the
 statically linked tools in /rescue did. So, I copied the statically
 linked init from /rescue to /sbin & tried to boot the system. I ploughed
 forward & went down in a flaming ball as various other tools which were
 critical failed to execute and I did not have a static version in
 /rescue e.g getty.

 I tried to roll a new release on NetBSD/i386 (running a stock build, not
 HEAD-LLVM).

 "ofwboot.xcf on the CD is non bootable an explodes shortly after
 producing the first line of test with the version / date the build
 happened. This issue was previously reported by jmmv on the port-macppc
 list
 https://mail-index.netbsd.org/port-macppc/2017/12/03/msg002464.html"

 ofwboot.xcf now fails differently, I get loadsize=0 adler32=1

 LOAD-SIZE is too small

 The image is odd in that I'm unable to extract some of the sets, systems
 complains about not being able to read from stdin during the upgrade
 process.

 I shall wait to try the next releng build from nycdn. The image should
 now be buildable.

 Yeah, I'm looking at the second problem right now.
