System: NetBSD thog 7.1_STABLE NetBSD 7.1_STABLE (THOG) #0: Mon Aug 14 09:33:54 CST 2017 oster@thog:/u1/builds/build160/src/obj/amd64/u1/builds/build160/src/sys/arch/amd64/compile/THOG amd64
Architecture: x86_64
Machine: amd64
>Description:
	

Attempting to build a LLVM-only build, with the following build options:

./build.sh -U -u -m amd64 -j 16 -V MKLLVM=yes -V MKGCC=no -V MKGCCCMDS=no -V HAVE_LLVM=yes -V MAKECONF=/u1/builds/mk.conf -D /u1/builds/build161/install/amd64 -R /u1/builds/build161/release -T /u1/builds/build161/tools/amd64 -X /u1/builds/build161/xsrc -x -M obj/amd64 release

resulted in the following errors, and a failed build:

>How-To-Repeat:
  extract netbsd-7 sources, and then:
  ./build.sh -U -u -m amd64 -j 16 -V MKLLVM=yes -V MKGCC=no -V MKGCCCMDS=no -V HAVE_LLVM=yes -V MAKECONF=/u1/builds/mk.conf -D /u1/builds/build161/install/amd64 -R /u1/builds/build161/release -T /u1/builds/build161/tools/amd64 -X /u1/builds/build161/xsrc -x -M obj/amd64 release

   please :)
