Well, usefulness of various parameters always depends on your needs. I
don't think that -vq is very useful or important (and especially not for
building the compiler) unless you specifically look for disabling certain
messages or automated parsing of compiler output.

Similarly, '-O- -gl -Xs-' are certainly not options to be always used for
building the compiler unless you want to debug some problem in the
compiler. Depending on your use case, users certainly may want to use
snapshots with optimizations enabled.

'NOGDB=1' falls probably into a similar category - if you don't have the
proper libgdb and are not interested in installing it (or it is not
available for the particular platform), you need this parameter, otherwise
there may not be many reasons for including it even when generating a
snapshot.

I'm sure there are other parameters which may be very useful depending on
the context (e.g. -vwih or even -va when solving compilation issues during
snapshot generation, etc.)...
