patch-utils_llvm-build_llvmbuild_main.py is missing a powerpc64 entry, such as
illustrated below.

The 2 powerpc (non-64) build attempts for clang 3.6 did not get this problem.
So this specific problem is powerpc64 specific.
Bootstrapping powerpc (non-64) clang 3.6 via gcc 4.8.4 (the current lang/gcc)
works fine. (In absence of any c++ port lang/clang36 automatically installed
lang/gcc (currently gcc 4.8.4) in order to bootstrap itself.)
Bootstrapping powerpc (non-64) clang 3.6 via gcc5 (by having lang/gcc5 already
installed first) still reports an error for not declaring ::sscanf, just like
powerpc64 based on gcc5 for bootstrapping did.
(This might be llvm/clang making use of only <cstdio> where an include of
<stdio.h> would be required to be involved in order to guarantee the ::
(global) declaration/definition. The way the C++ standard (all vintages) is
written gcc 4.8.4 and gcc5 could be this different and both be
valid/conforming.)

The problem:
portmaster -tDK --no-confirm lang/clang36 is how I started the build.
The error report was after it reported entering the directory:
/usr/obj/portswork/usr/ports/lang/clang36/work/llvm-3.6.0.src/tools/clang/lib/Driver/
The report was:
llvm-build: error: invalid native target: 'powerpc64' (not in project)
I'd be surprised if 11.0-CURRENT vs. 10.1-STABLE matters. But powerpc64 likely
does. I've not yet tried from a powerpc (non-64) FreeBSD build.
I'll note that with top -PaSCHopid I watched it compile the PowerPc code
generator software: it shoudl be able to handle PowerPCs fine.
My guess is a conversion of naming conventions is required someplace:
FreeBSD using powerpc64 vs. clang using ppc64. (Big endian context.)
This likely would matter for little endian naming as well (ppc64le on the clang
end of things I expect).

It used gcc5 to bootstrap as there was no clang present and that is the only
gcc port installed:
