ruby-3.3.0-preview1 does not build with BSD make without --with-baseruby. However, it builds fine with GNU make and when using BSD make with --with-baseruby. Previous Ruby tarball releases have built fine with BSD make without --with-baseruby, so this issue has been introduced recently.

When building with BSD make without --with-baseruby, building fails after generating RI format with:

/bin/sh:  false: not found
*** Error 127 in . (exts.mk:94 'ruby': @make   UPDATE_LIBRARIES=no EXTENCS=dmyenc.o BASERUBY=echo\ executable\ host\ ruby\ is\ required.\ \ ...)
*** Error 2 in /home/jeremy/local/ruby-3.3.0-preview1 (Makefile:948 'build-ext': @make -f exts.mk    libdir="/usr/local/lib" LIBRUBY_EXTS=./...)

This is still a problem in 3.3.0-preview2. I've been using the following bad hack to work around it:
