That's orthogonal.  The problem is that NETBSDSRCDIR cannot be
inferred for a randomly located kernel builddir and
sys/lib/libkern/Makefile.compiler-rt uses it.  I don't know enough
about sys Makefiles, but may be using $S instead of
${NETBSDSRCDIR}/sys will just fix it.  But may be will also break
something else.  Our makefile spaghetti is a bit out of control.
