I still get that error even with today's head, and even after running "make
kernel-toolchain".  All worlds (except riscv) complete and some kernels do,
but the sparc64 kernel fails and aborts the entire build when it does.  Is
this a related or a distinct problem?

 make[1]: "/home/asomers/freebsd/base/head/Makefile" line 697: "Target
architecture for sparc64/conf/LINT64 unknown.  config(8) likely too old."
