however, one can also generate a standard SDK with the generic

command will generate a standard SDK based only on what can be found
in the various .conf files and associated variables (MACHINE, DISTRO,
etc.) without being tied to a particular image.
just about to dive into the details, but is the above at least a
simplistic way of looking at it?
At the most fundamental level, you've asked bitbake to build
'meta-toolchain'. Looking in meta-toolchain.bb will show you what
that entails. It's basically just the compilers and a few other tools
that were added as needed over the years.
i'd assumed as much, but is there a reason that the meta-toolchain target
is not mentioned at all in the SDK manual? Would that not be the right
place to mention it, even briefly?
