How to build netbsd with pcc?

[Rhialto <rhialto%falu.nl@localhost>]

I saw a commit aimed at making compiler selection more general, so I
thought I'd try to do a build with pcc. Naively, I set HAVE_PCC=yes in
/etc/mk.conf, and MKPCC=yes and MKPCCCMDS=yes, as I saw on the NetBSD
blog.

Amazingly, that does go through some motions to build pcc
instead of gcc, but then it stops very disappointingly here:

dependall ===> tools/pcc
[configure output]
[compiles external/bsd/pcc/dist/pcc/cc/cc/cc.c to x86_64--netbsd-pcc]
install ===> tools/pcc
[installs x86_64--netbsd-pcc]
/home/rhialto/tmp/tools.amd64/bin/x86_64--netbsd-install -c -p -r 
x86_64--netbsd-cpp /home/rhialto/tmp/tools.amd64/libexec 
x86_64--netbsd-install: x86_64--netbsd-cpp: stat: No such file or directory

*** Failed target:  install
*** Failed command:

x86_64--netbsd-cpp /home/rhialto/tmp/tools.amd64/libexec
*** Error code 1

Stop.

What am I missing? I removed my obj and destdirs but not the tooldir.
