We may provide general way to detect whether builtin tool sufficient minimum 
required version or not,
as doing for texinfo and gettext-tools now.
It is unclear minimum required version for each tools now.
And some packages may require more newer version.
For Darwin, it may be handled in tools.Darwin.mk by ${MACHINE_PLATFORM} like 
for gmake,
but need to check and adjust after every new OS release.
Moreover, it is hard for Linux (PR#41822 probably came from too old builtin 
gmake on Linux).
