I cannot speak to your specific example, but yes in general there are
cases where you want a sub-make to not run in meta mode.
Using 'make -B' is usually sufficient.
Eg.
$ make -C bin/cat -V .MAKE.MODE
[Creating objdir /tank/home/sjg/work/FreeBSD/current/obj/i386.i386/bin/cat...]
missing-meta=yes missing-filemon=yes meta verbose silent=yes
$
$ make -C bin/cat -B -V .MAKE.MODE
compat
$
If you have a makefile that should *never* run in meta mode but you
don't necessarily want to run in compat mode you can put:
.MAKE.MODE= normal
in the makefile

The most common case where you want to use -B or otherwise supress meta
mode, is when you are using 'make -V' to print the value of some
variable.
