This is not a bug in make, per se, it's an error in the makefile. This
behavior is documented in the manual, where it says:
The `-n', `-t', and `-q' options do not affect command lines
that
begin with `+' characters or contain the strings `$(MAKE)' or
`${MAKE}'. Note that only the line containing the `+' character
or the strings `$(MAKE)' or `${MAKE}' is run regardless of these
options.
The makefile needs to not use the MAKE variable in a context where it
would do bad things given -n.
