I was (see above), and I think I've found the culprit. R_HOME/share/make/basepkg.mk is utilized by both the UNIX and Windows build, and its target mkR will expand the shell variable f to a suitable path under /tmp if TMPDIR is not set. Rtools' shell (forked by make) has no notion of a root file system at /, so /tmp is never found. The solution is to, of course, always set TMPDIR to a suitable directory before invoking make. Surprisingly, setting TMPDIR=/tmp actually works since make expands it to the user's temporary folder.
